Those are bare multisig outputs, which are in fact standard. There just is no address format for them.

If it's the standard, is there a place I can read more about it? Maybe it was introduced in some BIP?

Standardness is generally not specified in BIPs, as it is up to individual nodes to decide, and depends on the exact software you're using and what version. Bare multisig is accepted by most nodes, though.
