No, I agree with you.

Brings up a question. Is the list of all syscalls used by everybody
large relative to any one distro+platform-specific list?

Because if not, I could geet behand having *one* list and just
whitelisting syscalls until we stop needing to.

46 to 55.  If just 9 syscalls are the difference, the very slightly
reduced assurance starts to look like a reasonable trade to make the
whole problem go away.

Which, mind you, I wouldn't say if I didn't think we had done a
quite effective job of hardening the rest of the code.  But I *do*
think that - which makes this worth consideration.
