If you care about image size you need to switch to a distroless image base. It's incredibly easy nowadays with multi-stage builds. IMHO people use alpine not because they seek it out but because they're reading old guides and advice that hasn't been updated with the times.

Blindly switching to alpine to save space is opening yourself up to exactly these sorts of musl-libc quirks and issues--you better have solid test coverage and a plan to make sure there aren't unexpected edge cases.
