Who is talking about the interactivity of Emacs? Emacs might not be
the only application on the system.

Actually, yes. There are font-locking situations in stealth
fontification that don't finish immediately and even cause quite a bit
of sluggishness for Emacs itself.
But even apart from that, even if all font lock patterns for all modes
worked perfectly, this causes _considerable_ power drain whenever I
restart Emacs, reloading all files using desktop.el. The fan goes on,
blinking gets sluggish, and I notice that Emacs is eating my batteries
_again_.
Even if this worked perfectly (which it doesn't), we have no business
eating "stealth CPU" power in the default configuration since it is
near impossible for the user (heck, I am not exactly naive, and it was
impossible for me to find this on my own without an explicit pointer
after an error report) to guess just _what_ is eating her CPU.
