Why is gnu.gcc.org hosting work that is specific to some company's
build system?

Why is it necessary to announce a patch [series] for this branch when it
is intended that such a patch [series] make it to the trunk? Shouldn't an
employee of your company submit a `trunk'-worthy patch [series] for review
as would anyone else?

Isn't having one branch named `google' (or `google/maint') too ridiculously
generic to be of any use whatsoever? Wouldn't it make far more sense to have
a topic branch if deemed necessary (for, say, a large patch series)?

Why is gnu.gcc.org hosting such a pointless branch? Is it just that the
technical inadequacies of SVN made it easier for your multi-billion-dollar
company to host its essentially private work in GNU's repository?

Furthermore, looking at the `Subject' header of this email:

  Subject: Re: [google] Linker plugin to do function reordering using
                        callgraph edge profiles (issue5124041)

I wonder what `issue5124041' means. Is that a reference that only has
meaning for employees of your company?

Sincerely,
