The scientists have had this one right since 1927. Pure & simple, a "THOUGHT PROBLEM" solved logically.
5H shows headless H support Qxxx or xxxxx and a totally solid hand outside - PLUS at least one VOID!
Having a void confounds the use of Key-card Blackwwod, and how can you excpect to get to Exclusion Blackwood from here - the opponents are about to erupt and spoil your party.

5NT has already been mentioned.

You have different criteria for splinters in your contrived example, and possibly different criteria for using RKC at all. So, perhaps you are right. My methods won't work for you. The responding hand you give would neither fall into the narrow range of our splinters nor be a hand which intended at the outset to ERKC.

Ok, I didn't think it was obviously an EKCB bid of any kind, just a conceivable one. Can you give me a clear example of a hand which would do worse in the 'normal' EKCB approach though?

Will send a PM; we are off the reservation of this thread. However, the "normal" EKCB approach when (say) Hearts are trump and Diamonds are the exclusion suit starts with 5D gobbling much too much space and IMO is brutal.
