I hope so too.
Another point is that with asan-instrumentation-with-call-threshold=0
(instrumentation with callbacks)
we can and probably will allow to recover from errors (glibc demands
that),
but that does not require any compile-time flag.
I don't know details but are you absolutely sure that you won't want to
do inline instrumentation of glibc in the future? This would then
require -fasan-recover.
FYI in kernel we had exactly this situation: outline instrumentation
allowed us to hide recovery inside callbacks but then turned out to be
too slow so we are now switching back to inline instrumentation (which
requires -fasan-recovery).
