I haven't looked at the consing behavior, but I'll just mention that I find
stealth fontification annoying and have turned it off a while ago.
Many people have reported problems with it (typically they complain that
Emacs uses a lot of resources even when it's not used, which sucks when
you're running on batteries).
I haven't heard of any good reason why it should be enabled by default
(the argument that it forces us to fix it doesn't hold water since it
still hasn't been fixed after all these years).
