[flang-dev] [llvm-dev] [cfe-dev] Status of Bugzilla Migration

This thought had occurred to me as well.  Using a separate repo for bug 
tracking seems reasonable as an intermediate step.  Unless there's a 
complexity here I'm missing, I'd probably vote for that in favor of 
going all the way back to bugzilla.


p.s. Anton, thank you for the update and all the work that has gone into
