I believe there is a policy for micro-allocation from ARIN.

Speaking of which, is there no swamp space left unallocated, or available
for reclamation?

Using a /24 from an upstream has disadvantages; many backbones filter
/24s in newer address space, and if the site later changes upstreams and
drops the original one, they'll need to renumber.

Ideally, since ARIN has to deal with the new multihomed site anyway to
issue an ASN, a truly portable /24 could be issued along with it.
