It’s mostly just a recent issue that popped up. I’m currently running Ubuntu 20.04 (i.e. version from 2020, there have been two major releases since then) and since I use LUKS, resizing the boot partition is going to be fairly complicated, if I can figure it out at all.
AFAIK it already did happen to Linux, it’s just not as widespread (both Crowdstrike on Linux, and desktop Linux).
