I suggest changing the default value of `font-lock-verbose' to nil. The
fontification messages cause noticeable slowdowns on OS X[1] in certain
situations (e.g. viewing src code blocks in org-mode with
`org-src-fontify-natively' turned on). I suspect that the sorts of users
who might appreciate the output would be able to turn the variable on.
Thanks,
Dan

Better to fix those "certain situations" on OS X. Or, barring that possibility,
change the default value to nil for OS X only. Consider filing a bug.
IOW, why change the default value for all of Emacs because you ran across a
problem on OS X? You say that the problem is platform-specific. So should be
the remedy.

I'd tend to agree. I can't think of any reason the user would care
about those messages. They're much like "garbage collecting" messages,
if you ask me.

Sounds like a bug that needs fixing, rather than a reason to change the
default of font-lock-verbose.

Agreed.

FWIW, I use Emacs on Windows. Having zero verbosity does improve the
user experience tremedously.
Speaking from Windows side of things, I second Dan's recommendation.

ISTR a "huge performance increase" in garbage collection that came about
solely as a result of making garbage-collection-messages default to nil.
Perception is important.

I don't remember such a huge increase, but I do remember an immediate
stop to the recurring lament that "Emacs is slow, because of GC".

Amen,
