It seems to be based on very common naive belief that things which are named same or similar in different domains are conceptually same, so "lets deduplicate" ? There can be rare moments when they really are, but then the moment passes and then you only have troubles.

To me the motivation seems more along the lines of "we build lots of different systems that deal in the same domains" (because they are deep in microservice land, have apps for all kinds of platforms, ...) "lets make sure they all use the same definition of the things". Do you think that doesn't make sense (because each of those should be considered their own domain?) or does something else give you your impression?
