Answering my own question, just for the record. I just tried it, and
there is no need to actually have the module in the LPA chain. SVCUPDTE
does indeed update the SVC table, and the SVC can be executed with no
problems.

Subject: Question on adding an SVC routine dynamically to a running system
The auth services guide in the chapter on user SVCs, states a type 3
needs to be in LPA. Yet the SVCUPDATE will accept, and update the svc
table, an address in ECSA. Do I need to add the routine to LPA using
CSVDYLPA prior to SVCUPDATE?

If the intent was a permanent change, just be sure you DO get
appropriate parmlib and/or module location changed before next IPL, so
you don't get surprised by unexpectedly losing your updated SVC at next
IPL. I always tried to do both updates at about the same time under the
assumption that Murphy might arrange for unscheduled IPLs at his
convenience, not mine.
