The delay at the beginning is long, and it might be annoying
when org pulls in a buffer just to look something up,
without org-inhibit-startup scoped into the file loading.

Maybe one could arrange for the initialization to happen just
before the buffer is first *displayed* (I do not know if that
is possible).

Just one nitpicking:  The idle timer may force updating when
not necessary - but using after-change-functions will update after
each character inserted.  So in fact your code might be updating
more often at least while typing - maybe not while looking at
the buffer and jumping around.  I am not a fast typist, but maybe
fast typists will notice significant delays, in particular
while writing inside a very long section?
