well, this has been debated at length during the WEIRDS working group 
work. I actually wrote a sentence about this in the RFC (in the 
acknowledgements section). I’m not sure we want to restart the debate 
again…

yes. this is the well-known caveat of this RFC and discussed and debated 
during WEIRDS. But experience up to now has not shown any issue, at 
least to my knowledge. (and as a developer of the RDAP Browser mobile 
app, I haven’t seen any issue fetching that registry. I do have found 
thousands of issues with the registry/registrars RDAP servers however, 
but that is another story).
