I didn't know that Samsung had that feature, but it does sound nice - so long as you have the ability to enable maintenance mode.
I recently took my pixel 7 in to ubreakifix for a screen replacement. The screen was 100% dead, but I could still hear the notifications coming in. I couldn't put it into maintenance mode if it had one, so I think I'd still stress a bit about whether or not the phone would be wiped, such as in the case I was unable to verify the upload of a recent Aegis backup. It would be nice if the maintenance mode was able to be triggered via a web interface in cases such as mine. Or maybe even a specific button combo that would be difficult to accidentally do.
That's a good point, and I agree: There should be a way to trigger Maintenance Mode remotely, like through Find My Device, should Google implement this.
