If a css tweak would be sufficient: I’m hiding both default admins and moderators on our /about page and then show everyone who’s actually moderating by having a dedicated group that shows up using category moderation (About - Forum | Couchers.org). You could do something similar with a “Community Leaders” group for your tl4 users.
@pfaffman you could also hide yourself with a line of css until you find time for a plugin 
.about-page .about.admins .user-info[data-username="pfaffman"]{display: none;}
