Inaccurate. First, font-lock was turned off by default in _all_
versions of Emacs since its introduction (in v19.x, AFAIR). More
importantly, a large majority of users turned it on, so that
jit-lock-stealth _was_, indeed, widely used since v21.1, where
jit-lock was introduced.

Inaccurate. Improvements to jit-lock notwithstanding, the main reason
for turning it on was that we decided the garden-variety CPUs are
nowadays fast enough to fontify buffers without annoyance to most
users.
