I'd defer to any real scientist, but warming vinyl (up to some point which I don't know) might make it less susceptible to damage, not more.
Cooling vinyl to below room temperature reduces its elasticity. Vinyl subjected to impact stresses in that state will more easily chip or crack.
Warming vinyl to (somewhat) above room temperature presumably increases its elasticity. Vinyl subjected to impact stresses in that state would flex, then return to its original shape.
If the above is correct, *slightly* warming an LP should reduce the likelihood of stylus-induced groove wear or damage.
Caveat #1: there is *some* temperature above which vinyl loses its elastic tendency to return to its original shape after being deformed. Hot vinyl behaves more like a liquid than an elastic solid. This explains why LPs are made by pressing hot vinyl into a mold, and why the vinyl must be allowed to cool before removing the mold.
Caveat #2: warmed vinyl might be less susceptible to stylus-induced wear or damage, but the sonics of a softer groovewall would certainly be softer too; less HF information, less low level detail, softened microdynamics.
It's a compromise, like eveything with this wacky, loveable medium.
