I routinely don't want persistent mount points. Imagine my: cryptsetup luksOpen /dev/sdXY name
Followed by: mkdir -pv /dev/shm/name
mount -o noatime /dev/mapper/name /dev/shm/name
What this "RemoveIPC" did for me was rm -rf all of that, even if I mounted them as root.
That a single "RemoveIPC" difference between openSUSE 15.2 and 15.3, undocumented, caused me to lose all that data is one thing.
Another thing entirely to question WHY "RemoveIPC" is even a thing to begin with. I have never logged into any machine and said "wow look at all of this stale data taking up RAM in /dev/shm".
