How awkward would it be for an end-user who's on OpenBSD 7.1 to
build a QEMU that doesn't have libslirp? (That is, is it easy
and common for an end user to pull in a port of libslirp that only
came along in a later OpenBSD, or would they instead have to
manually compile libslirp themselves from the upstream sources?)

(I'm asking here because if it's painful, then we should perhaps
defer dropping our submodule copy of libslirp a little longer.)
