No, that isn't possible. As you say, you'd have to script something
around it on the client side.

Correct. Bv9ARM section 4.5.5 specifies that ACL definitions for
allow-{query|transfer} have been extended to allow TSIG keys, but there
is no mention of SIG(0) keys.
I use SIG(0) for granting updates, and TSIG for restricting AXFR.
