At least ETSI differentiates between CAC and Off-Channel CAC, with
dedicated requirements for times and detection probability for
continuously monitoring the operating channel vs. accumulated periods
listening for radars on a different one.
OC-CAC is considered as an optional optimization to enable switching to
a new channel without the need to perform a CAC there. Weighting the
potential gain vs. the required effort to support that feature, I'd
assume OC-CAC is not a hot topic (maybe even not feasible in the long run).
