to answer my own question:

Recently it was pointed out to me that there is a
"RDAP Operational Profile for gTLD Registries and Registrars" and
given that ICANN therein demands to use the ROID (resp. the Registrar
IANA ID) and NOT an EPP-handle as i initially assumed, my question is
moot.
At least using the ROID or GURID is consistent with the WHOIS clarifications.

thanks,
