I dug up the original ticket for this from 2016 which has some interesting thoughts on the topic: T133381. The use case we have now is different from what the one this ticket was created for, but a few of the points are still relevant.

I'm trying to think of the possibilities for "how to solve this in the action api".

I think if we are to use entity prefixes there we might also need to expose them in WikibaseManifest or somewhere else.

Otherwise how can an api client wishing make statements using properties about wikidata.beta.wmflabs.org know that on this wiki the prefix is wikidatabeta rather than wdbeta?
