A "delay" of, say, 0.01 seconds is indistinguishable from zero.

Did you try decreasing the interval to  low enough value?  If not,
please do.

File notifications are not immediate anyway, because they enter the
Emacs input queue.  Which also means that if Emacs is busy doing
something, the buffer won't be reverted until Emacs is idle.

So I see no real advantages in your suggestion over what we already
have.
