My non-expert take after reading a few things off the ever reliable
Internet is that there's no need.

SSDs degenerate over time, picking up (permanent) bad sectors. But it's
handled gracefully by the SSD's firmware. Changes to fstab are designed to
lighten the 'wear' on the SSD. But in the real world even if you crunch
data through a SSD drive as hard as you can 24 hours a day it'll still
likely last longer than the life time of the rest of your hardware before
the firmware can't cope and you start noticing reliability issues from bad
sectors.

There might be some RAID issues that someone more knowledgeable than me
could comment on - but even then the worst that could likely happen is that
you re-format and re-install once in a blue moon.
