My most recent observations of discussions around DNS over QUIC and HTTP/3
was that some folks had attempted DNS over HTTP/3, however the overheads
(~14KiB for a query at worst-case) made it impractical and infeasible. With
regards to DNS over QUIC, the current dprive working group adopted draft
[1] is focusing on stub to recursive, but not necessarily as a multiplex
with an existing QUIC connection.
