Why this change? Writing to it will be faster than disk but idk if am is a precious commodity I’d rather it was just a part of the disk I was writing to.

It's a dumb idea that came from the systemd people. They've never explained properly why it's a good idea, but it's the systemd default and for some reason distros defer to that.

Not at all. tmpfs precedes systemd for like a decade.

It only became the default on Fedora and other Linux distros following systemd because it was the default in systemd.

It was a bad idea on Solaris too, but at least back in those days the trade-off between RAM and disk storage was very different from today now we have NVME drives and such.

Oh no, tmpfs was introduced and used way before systemd.

I'm well aware. I used it on Solaris.

Solaris/SunOS. Oh those were good times. Cheers, mate!

Which was contested by no-one. He complained about systemd switching /tmp to tmpfs, not systemd people making or causing tmpfs in general.
