Admittedly, a more principled approach would have been to add an
SHF_COMPRESSED flag to ELF without changing the section name, but the
".zdebug_" approach matches what was done a few years ago for ET_EXEC
files. It's also easier to handle it that way in the non-ELF file
formats.

Yes. There's a BFD flag that lets the client specify whether it wants
to see the decompressed contents or not. If you're asking for
relocated section contents, it'll decompress first.

Right.
