[WikiEN-l] Should anons edit Wikipedia:Semi-protection policy?

[Ligulem]

What's the purpose of letting non-autoconfirmed accounts edit 
http://en.wikipedia.org/wiki/Wikipedia:Semi-protection_policy?
(other than causing work for others to revert the 97% crap and making 
noise on watchlists)

Why can't we simply semi-protect that? (Or do we need yet another policy 
for doing so?)

Or is this a wiki-religious thing?

Puzzled,
