I think that umarells are an interesting phenomenon. They sound like they were annoying construction workers (bikeshedding) but rather than treat them as a nuisance (loitering->fines or jail), a purpose was found: they get paid an honorarium for "jobs" most of us would find eyewateringly boring but provide value for the construction companies.

Well, they don't annoy workers, not that much. They may exchange some word, probably opinions on what's the best way to do the job, but they are mostly quiet and observing.

Because often software teams have one or two Umarells among the members.

It isn't rare to have teams consist exclusively of Umarells. Usually this is the result of evaporative cooling.
