Disambiguation tags were an experiment that seems to have failed completely. They're not getting cleaned at all.

I don't think the admins are too keen on adding more of those.

The main problem is that most of them are way too big for an average user to have any motivation to bother fixing them and the handful of dedicated taggers we have already probably already have a to-do lists of tagging projects that they're already dealing with so these tags continue to get bigger and the cycle repeats.

Unless we find a way to discourage peeps from adding these tags to images or at least notify them when they do add a disambiguated tag the problem is probably going to keep getting worse.
