I don't understand why you think so.  It's a detail that should be
purely internal to jit-lock.el (and which should have no impact other
than in terms of performance).

E.g. it shouldn't affect those people writing packages which rely on
jit-lock (it doesn't change the rules of what to return in
`jit-lock-bounds`, for instance).
