I've just stumbled on this new warning and I disagree with the
recommendation. Sometimes we just filter out garbage from the upstream
sources and we don't want to add a +repack suffix.

This is a very common pattern in the Java team where .jar, GitHub CI and
IDE settings files are frequently removed and we don't want to fiddle
with the version to keep things clear and simple.

I suggest changing the severity to info or pedantic, and adjust the
description to explain the suffix is optional.
