Re: why editors can't edit their own locked userpages:

Several very good reasons exist for not letting a particular user edit their own user page. Most of them relate to posting of malicious or objectionable content, like spam links or personal attacks. Since personal userpages tend to change infrequently, the reason for the lock usually is usually temporary, and most frequently locked userpages belong to admins or staff... It's usually easier to have any non-admin with a locked user page coordinate with an admin if they need to make edits to their page (either by temporarily unlocking the page or having the admin make the edits directly). It's a lot more burdensome to change the coding to the username pagespace.

-- Re: Universal userpages tangent

I think you're misunderstanding the fact that the userpage on each individual wiki may need to be very different. While there are some aspects that may be shared, not every wiki will want to know the same information about an individual user.

For example - a Pokemon wiki may want to know if I've got a full pokedex, a chess wiki would be more interested in my Elo score, and a robotics wiki might be interested to know if I was part of any teams or competitions involving robotics. A Harry Potter Wiki may want to know whether or not I'm part of Pottermore. However, the pokemon wiki won't care what my Elo score is, the robotics wiki probably doesn't care how full my pokedex is, and nobody other than the Harry Potter wiki will probably care if I'm part of Pottermore.

Also, some wikis may wish to add specialized content to a particular users userpage. For example, special projects, kudos or warnings for behavior on that wiki. Examples might include: "This member is a part of the FISH project, committed to monitoring and upgrading all articles associated with PROJECT FISH'."; a user that is repeatedly posting unconfirmed content about an upcoming game to an article page may have something saying, "This user has been banned from editing article Y for X time because of repeated violations of policy Z. Please see Policy and Guidelines, section Z for more information."; someone who has been especially kind may have something saying "Barnstar: this star is for going the extra mile to be nice, and teaching User:Name how to make a new custom infobox template. Awarded by USERNAME on DATE".

FYI - global/universal userpages are already possible. They're mostly used by Staff and VSTF, but anyone can make one... You just need to go through a few extra steps. Contact me on my message wall if you can't figure it out for yourself.
