I think in my refactor this became !features.RecursiveReadOnlyMounts3.Enabled() . I guess the advantage in this refactor is that every featuregate has the env var assignment? How attached are you to the feature.Enabled ?

I don't see why we wouldn't want ALL gates to have the same enablement options?
feature.Enabled( syntax was JUST to put the verb at the front of the LOC. I find it easier to read as:
if !feature.Enabled(longpkgname.bigLongVariableName) {
than
if !longpkgname.bigLongVariableName.Enabled() {
That's REALLY the only argument :)

I prefer the more explicit FeatureGate and FeatureGateSet (or FeatureSet)

I was trying to follow the "don't stutter" approach. feature.Gate vs feature.FeatureGate or heaven forbid featuregate.FeatureGate.

I see an advantage to using an interface over a concrete type here so that in composition people can say, "David and Tim won't are too slow to merge my awesome way to set FeatureGates, so I'll provide a compatible implementation myself!" and anything accepting a GateSet will "just work".

I see that as exceedingly unlikely, or at least not super compelling vs. the complexity. Using interfaces has a few costs, IMO:
- Harder to keep in brain
- MUCH harder to back-track to "where did I get called from"
- Requires everything be methods, meaning the types get more obtuse
- Encourages defining more and more interfaces when a "dumb" struct would do
- Encourages "SimpleFeatureGate" stuff which makes it more difficult again to track
Aside: I looked again at your branch and I honestly have no idea what a private method in a public interface means :)
I won't die on this hill, probably, but this seems like the sort of API where simpler really is better.
I'll try to take a pass over this variation and see if there's a not-so-bad way to have the best of both

Pinning apidiff to a specific version shouldn't be necessary because, if past experience in klog holds true, the latest version just works. This way we don't have to remember to bump up the revision. The downside of using "latest" is that a compromise of that version would give an attacker the ability to run code in the CI and on developer machines.
Refactor the TestValidateKubeProxyConfiguration by adding a mutating function that adjusts the configuration according to each test case, thereby enhancing readability. Signed-off-by: Daman Arora <[email protected]>
During upgrade apply we had logic to download the kubelet and kubeproxy configs from the cluster as part of the call to: FetchInitConfigurationFromCluster() With the introduction of UpgradeConfiguration there was some refactor in this area and the function no longer had the argument skipComponentConfigs set to false. It is set to 'true', an InitConfiguration is downloaded but it would contain empty / defaulted component configs. - Set the argument to 'false' - Perform minor cleanup of STDOUT messages and comments. that were missed in 1.30.

This commit demonstrate how libraries can define and expose Gates and GateSets, and compose GateSets into new GateSets. It also defines a small number of new-style gates, but does not use them yet.

Notes:
Some of these parse into a map in their config and then call SetFromMap -- need to retain ability to pass in via config.
Option 1: make a `feature.EnableMapControl()`
Option 2: pass map into `feature.EnablePFlagControl()`
Option 3: `feature.GetAllGates(feature.FromFlags(flagName), feature.FromEnv(prefix))`
This is probablay most correct today and makes validation easy,
since we do it exactly once. A little awkward with any dynamic
source (e.g. API).
Should env enablement be part of "AddFlags" logic in these components?
It's a little muddy how apps are configured.
