The intention was:
P and Q indicate the *type* of the entity ("P" = "Property", "Q" = "Item" for
arcane reasons), "L" = Lexeme, "F" = Form, "S" = Sense, "M" = MediaInfo). As you
can tell, we'd quickly run out of letters and cause confusion if this became
configurable.
Using prefixes to indicate where the entity comes from is indeed useful and is
already part of the model. The prefix for Wikidata is "wd:", wo "wd:Q12345" is
an item from Wikidata. The prefix can be omitted for local entities, so Q12345
is an item on the local repo (or the default repo of a wikibase client).
