Yes absolutely. Atomic look around is very useful... and i'm not sure if Extended regexp supports non capturing sub expressions... i.e. (?:stuff). I wonder how difficult it'd be to work in named captures... /(?<request:Stripped-User-Name>[^@\\/])/...

Regular expressions are a bit of crutch in unlang, they do the work of chomp/split/substr etc, so the more powerful and feature-full the better.
