Blocks exist to keep things simple for allocators (i.e. UTC and WG2), and
not to allow end-users to make deductions about them; all such deductions
are quite illegitimate. (If this isn't actually written down anywhere,
it should be.)

ISO 10646 (but not Unicode) does have the notion of labelled collections,
which may be open (i.e. include currently unassigned codepoints) or closed.
Regrettably, I can't cite examples, as AFAIK the list of collections is
not online anywhere.
