Why is everybody being CC'd, even if the bug has nothing to do with the
person's subsystem?

The To list should be intersection of 2 groups of emails: result of
get_maintainers.pl on the file identified as culprit in the crash
message + emails extracted from the bisected to commit.

There is "#syz uncc" command but it is too hard to utilize?
