pgping can be fun. a pgp server would be cool to have. New players won't like to pgp because they would die to fast, but they would get better.
I agree they might not like it.
However, they should. First of all they rarely need to switch out the CO2 or ammo, which is annoying for beginners. Moreover since new players can't jump as well and can't often easily gain access to the best weapons this levels the playing field as much as possible.
It also helps them aim and teaches them a style other than lining. So while they may not like it, it might actually favor them more than one would think.
