Wise? meh... Can't hurt.
I end up laying mine down on rocks and all sorts of schtuff, so just about everything gets scratched after the years no matter how carefully its handled.
(Never fails that the time I ever so gently lay my stuff down on a padded surface, someone walks by and knocks my stuff over
(I do lots of pet photos, so by "someone" I likely mean a 100lbs untrained dog on a leash held by an owner that doesn't know how to handle the animal. ugh...)
Anyway, I use some old screen protectors left over from my old "Palm Pilot" days of the early 2000's. Tough stuff.
And if the back LCD should ever break, it will help hold the glass bits together.
