As a user, I remember the era between 2015 and 2020 where GNOME Shell's video screen recorder was *literally unusable* because the VP9 encoder could never keep up and would lock up your computer by filling up the RAM within a minute. I'm not making things up; this commit proves it: https://gitlab.gnome.org/GNOME/gnome-shell/-/commit/c61685e617
So, *very much* a technical limitation.
I would have appreciated if you had simply asked politely to begin with, & assumed good faith, rather than immediately publicly smearing #GNOME
