The point is that it's easy for somebody already looking for support in
the first place to get frustrated when they have to jump through another
hoop to get there.
knowing the ops and what they have to deal with, the registration process is mainly for managing the channel from spambots and the like. i'm certain if there was another well-functioning way to ward them off that they would go that route. it is designed to make the whole support experience better in the long run, even for the n00bz who end up in there.
anyone who thinks registration should be removed needs should be willing to commit to a few hours each day being an op in the channel. that job is not as easy without that spambot safeguard.
