This is the first I had heard that people objected to using a TXT record, but I might have missed that part of the discussion. Given that this query is for a newly-created SUDN that is only used for looking up DoH information, there is no chance that the TXT record would be in use for anything else.

Having said that, it would be quite easy for this document to create a new RRtype for this particular query. (I would not want to re-use the URI RRtype because it would take more effort to explain the priority and weight, as well as dealing with the common error of people not put the URI in quotations marks as is required for the URI RRtype.)
