It might be that I'm already too sleepy, but I don't see why
a faster comparator would add more jitter. Actually, my intuition
(which is clearly wrong) would say the contrary. So, which effect
does increase the jitter with comparator speed?

Well, for that you'd need to understand what an oscillator
actually is and how it works. The knowledge of that is
hardly taught anymore. And those people who know how to
properly design an oscillator are either nearing retirement
or are already retired.
BTW: If anyone here has any good text to read on oscillator design,
please let me know. I'm collecting those :-)
