I would say that this is a bit arbitrary to think
that signals are "not relevant". In many cases,
they are!

The suppression done by -q was suppressing messages about
what _strace_ does, those messages had nothing to do with
_what happens to the traced process_.

Your new addition suppressed signal delivery log messages,
and that is something which _does happen to the process_
being traced.

Also, your addition is unnecessary because "-e signal=!all"
does the same thing.
