ah, I just saw this one:

--snip--
commit 8427c797cecc88d70bdee4f310351ca3d4c310db
Author: Garming Sam <garming at catalyst.net.nz>

lib/param: set default for -valid parameter

This parameter isn't used in any of the lib/param code and is being added for consistency

can we revert this ? initializing a weird parameter which is not
used and for which we actually have a different one anyway doesn't make much
sense to me. Or did I oversee something, Garming, Andrew, Michael?
