Yes, there's some ongoing discussion in bug #444659

I tried some time ago to make smooth scrolling work through GtkTimeline,
but couldn't make GtkTextView behave nicely with it, its exotic usage of
adjustments broke cursor handling when scrolling with the keyboard. I
still have to test this patch to see whether that still happens, if it's
necessary, I got some code towards fixing these.

Regarding using the timeline, it probably makes sense, although it was a
bit strange to use for animations with indefinite (and constantly
changing) duration, maybe it should also allow specifying an infinite
duration, so it can be stopped at any time.
