Depends on what else is in the buffer. If "one more stop-point per
line" adds significantly to the number of stop-point (which I think it
will in many cases, as code typically has few different faces per
line), it will be measurable, yes.
And using text properties for this kind of information is really not
clean. It also comes with technical problems, because text properties
cannot overlap. As I wrote earlier, I'd much prefer some buffer-local
variable.
