Are you sure it will restore the font-lock state or is just that
the normal find-file hooks us the normal mechanism to turn it on?
The latter.
i.e. what happens when I am editing in a major mode that is normally
_not_ font-lock-ed an I do
M-x turn-on-font-lock RET
I presume you mean M-: (turn-on-font-lock)
M-x revert-buffer RET
Is the result a font-locked buffer?
No. Which is as it should be[1].
I guess my wording is confusing. I mean that the normal mode hooks
will turn on font-lock if it should be turned on.

to any other version) FSF Emacs 20.3 works the same way.
