I fully agree. I rather see the scarse development resources being focused on fixing this, than the p/q business, as you nicely call it. Tbh, I really don't see an issue with multiple p's and q's over different Wikibases. That is where prefixes are for, to distinguish between different resources. Examples of identical identifier (literal) schemes between multiple resources are abundant. (e.g. PubMed and NCBI gene) It really is a matter of getting used to, or am I missing something?

What is more problematic than the p/q business:
If I run a SPARQL search at our endpoint - such as this one:
https://database.factgrid.de/query/#SELECT%20%3FIlluminatenorden%20%3FIllumi...
I will receive answers in the form of
wd:q25
but they do not lenk to wd, wikidata, but into our database https://database.factgrid.de/entity/Q25.
The same problem in the other direction: If our users have never seen a SPARQL search in their lives (and that's 100%) and if they now click at sample queries - they will qet Wikidata sample queries which do not work on our database - just as our P and Q numbers do not match.

It should also be made possible for the local wikibase to use local

I think the opposite is the case: ending up with a zoo of prefixes, with
items
being called A73834 and F0924095 and Q98985 and W094509, would be very confusing. The current approach is to to use the same approach that RDF
and XML
use: add a kind of namespace identifier in front of "foreign"
identifiers. So
you would have Q437643 for "local" items, xy:Q8743 for items from xy, foo:Q873287 for items from foo, etc. This is how foreign IDs are
currently
implemented in Wikibase.
