Hmm, my script is very young.  No particular clustering yet, I think.
I use the feature for implementing conversions that are not too well
documented (few words where the effect can be seen) or unstable
(several parallel forms are attested) or different for different words,
so that I can manually choose which way a word goes.

I'm a bit easier off -- implementing local flags is tricky when running
the sound changes backwards, which I never tried for my tool.
