I suppose a bit of both, but mainly for practical reasons of wear and maintenance.

As far as wear, realistically I guess it would be no different than applying clear lacquer or poly to a maple fretboard, but it could make future fret replacement trickier.

If you got any tear out when removing the frets (which is always a risk no matter careful you are) fixing it could be more difficult to touch up than just a clear coat. I don't think I'd take it on if someone brought it to me for a refret.
