Expanding the indexing system so it doesn't depend on AdultWork profile links has been on to-do list for more than 2 years.
The problem is it's not straightforward, the code for the current system is all over the place spread over many files. And a number of external scripts depend on the current system / database schema, so they all need to be upgraded in one go.
That's not to say I don't do anything on UKP outside of moderating, the past month I've spent over a dozen hours extra time on backend server improvements and fixing minor technical problems with the site, it's just not apparent anythings changed from the outside.
The issue is I don't have much time these days on UKP/UKE/PW as I am busy with other things. I have a number of improvements that are 50-80% completed (helpful new features that would be highly appreciated), I just don't have time to do that tiny bit extra so they're completely ready.
