Any suggestions for what to remove from that page? I agree that it is ugly, but the only things I see there that are irrelevant are the createacct-benefit-* system messages.

Wikitech accounts are really Developer accounts, and as long as we are allowing them to be created via MediaWiki rather than only dedicated tools like Striker its hard to see how to add the various disclaimers that have been requested over the years in any other way. The orange box in particular was added because of T172650: "last" command on WMF Labs/Tools allows users to view IPs of other toolforge users to help people understand that using a Developer account does not grant the exact same privacy model as a "normal" Wikimedia editing account.
