Yes, this is not a reliable solution since an idle timer may fail to run
at the requested time.  I think your first idea is better.

I wonder why standard timers don't do something like that: run a function
after a long timeout (e.g. several minutes) but only if Emacs is idle for
a few seconds.  This looks like an useful behavior.
