Use of defaultRevision field for injection

[dgn]

I noticed we added a defaultRevision field way back in 2021 and it seems to make sure to point the ValidatingWebhook to that revision, which I think is cool when doing canary upgrades. It doesn't however affect injection - I would have expected that if I set the defaultRevision to a revision, it will allow me to use the istio-injection label again (instead of having to use istio.io/rev), but that doesn't seem to be the case. Is there interest in that? If so, I'll implement it

I had thought for sure this was how it works. Is that not the case?

I recall we were using it for this purpose in a former deployment i worked on, but maybe we had some customization..
