One thing that I was thinking it'd be nice to see about getting
into 8.1 was the DWARF5 index stuff (standard replacement for 

Not sure about making that the default (seems risky), but it
might be nice to provide the option so that users/distros can
start experimenting (and so that Fedora/RHEL doesn't end up
having to backport yet another large series... :-P) .  I tried
to review that in the past but stumbled  on choices I didn't quite
understand, and there are also some open questions, but I was
planning on taking another look.  I can't really promise I/we can
get it done this week, so not sure about blocking the branching
