Can one achieve this by telling LVM to allocate less than the full size
of the device to the PV one puts on it?

If one does that, I would guess that one could later extend the PV to
use more/all of the disk using pvresize, so that those that prefer space
over endurance could make that decission when they are running out of

If that's all true, we could have a couple of preseed variables to set
the percentage and maximum amount that would be left fallow for this
purpose, and (eventually) set non-zero defaults when installing to SSD.

Is that something like what you're after?

Cheers, Phil.
