I'm afraid i have to completely disagree. When they come to a stop, they are blurred (on a 4k monitor at least).
Worse than that, they take up an inordinate amount of space, before todays additions, if you wanted all of them enabled, you would already have been using 11gb of space, so who knows what they take up now, probably north of 20gb.
Most people using apple silicon have only 256gb ssds, and even at 512gb, who is realistically going to use 5% of their ssd space for some screensavers. Granted, you could just use one but that gets dull pretty fast.
On top of that, these are not easy to disable. Even if you do just select one, your mac will download more/all in the background whilst you are using the machine. I have disabled it now, but it took a bit of trickery using little snitch.
