No. The suggestion is for the LF to setup mirrors for glibc and other
Sourceware hosted project git repositories. That would be something
nobody would find controversial and would be genuinely useful.

GCC is bigger than most other Sourceware hosted project repos, but not
the biggest. Take a look at the libabigail-tests, abidb or bunsendb
git repos for something that is.

Sourceware hosts a lot of git repositories both really small and
really big. So concretely if the LF wants to help out in a
non-controversial way then they would make everybody really happy by
setting up mirrors for all of them.

The 54 repositories listed here:
https://sourceware.org/cgit/
The 3600 cygwin repositories listed here:
https://sourceware.org/cgit/
The 3 gcc repostories listed here:
https://gcc.gnu.org/cgit/
And the 4 DWARF standard repositories:
https://git.dwarfstd.org/

Let me know if they are interested in that and if we can set things up
to make that as easy as possible for them.

Cheers,

Mark
