While browsing lib/src/random.c, I noticed that we've had the "dir" parameter to mrandgen for a LOOOOOOOOONG time (if my reconstruction is correct, since 2022a). For example <hansl> matrix D = mrandgen("dir", {0.4, 1.2, 0.8}, 16) </hansl> It would seem that we forgot to document our ability to draw from a Dirichlet distribution; the Changelog is silent on this too. I can't find any email exchange on this subject. Does anyone remember if this was a conscious choice (maybe, insufficient testing), or did we just forget?

So maybe add a comment to the source there?
