It is not hypothetical [1]. I have reported issues with overlays in
org-mode in the past. Also, from my experience, large number of overlays
appear to cause garbage collection issues and overall Emacs slowdown.
Is the overlay branch ready to be merged? I am only aware about yet
another effort to revive it back in 2019 [2]. Is there any progress
since then?
Best,
Ihor
