> 1. What are those affected tools? Will they be fixed? When?

I don't believe any non-binutils tools handle gabi compressed elf sections yet.
In particular elfutils tools don't handle them. elfutils libdw does support gnu
compressed debug sections for ET_EXEC and ET_DYN files, but not ET_REL files.
elfutils libelf doesn't support any compressed section type currently. There is
some work on supporting compressed sections for libelf, but that needs some
coordination with other implementations and won't be in any release this year.

none.

I think the default should be the same for all tools, but making it possible to
configure them with different defaults won't be bad.
