Other highlighting mechanims have speed issues as well.  For example,
Gnus prefers not to highlight huge messages because that would take
too long.  If I controled that with `M-x font-lock-mode' (which would
buy me nothing in turns of convenience; Gnus has variables to
fine-tune its highlighting), I would expect things like
`font-lock-maximum-size' to keep working.

Plus, font-lock-maximum-decoration is not only about speed.  Some
people don't *like* too much decoration.
