That's what tracer is for. My earlier comment was to ask if you were
aware of some problem with tracer, but you've since clarified that you
don't use it, so the question is moot.

Most apps don't care, but tracer will tell you anyway and let you
decide.

Also, I usually have a VM running (Windows 10) that I prefer not to
have to restart just because I updated one of Linux's libraries that
the VM doesn't depend on. This might even mean restarting my desktop
session, which I can do without the VM even noticing. Forcing updates
to be done offline is using a sledgehammer to break a nut.
