I've been trying to think this through a little:

Binutil's schedule is roughly one release per year.  GDB's schedule
is usually 2, but can depend on new features. I don't think that GDB
is thinking of changing the frequency of its releases, so unless
binutils switches to two releases a year, the two projects are not
even on the same schedule. And the release numbering is also different.

Also, finding a branchpoint for a release branch has never been easy
in the past, and having to now consider both binutils and gdb for
creating that branch is only going to make things harder either by
delaying the branching, or by creating more backports.

I think that it would be an extra burden for both projects, and
at the same time, I am not sure I am seeing how it would still
be beneficial for both binutils and GDB to be adoption these
shared release branches. Maybe it's because I don't see why using
a combined tree is making things any different?
