Strip all binaries for slim images
This might be something you would do for the slim variants, but please don't do this for every image. Alpine is already slim enough.

Sure, done.
Though the size reduction for alpine is even better in percentage: 90M -> 67M. Is there a reason not to strip?
Sorry but you should await feedback from @tianon here. My point is, slim images are designed to be small, but the non slim ones, if a linux binary is expected on the live system, then people will also expect it in the docker image, so this might break people's expectations.
- alpine is slim by design
- What do you mean by expecting a linux binary? I didn't delete anything here, only stripped debugging symbols. All package managers do this.
This might be a breaking change so it might be bettter to do for a new version.
What do you mean by a new version? Aren't the docker images tagged separately?
The difference with package managers is that they typically provide something like dbgsym packages that can reinclude the debugging symbols external to the binaries, which is very difficult for us to provide effectively, as seen/discussed in https://github.com/docker-library/php/issues/1538 (and linked issues), so I'm hesitant to opine on whether this is generally reasonable for us to do.
You can create another image variant with -debug.
Have you ever used the debugging symbols in the image?
