There are no issues there.  HTTP/2 introduces new constraints on the
implementation, in particular with respect to the use of TLS, but as
long as those new requirements are met, then HTTP/2 is perfectly
suitable for use with HELD.  (The same applies to LoST.)

The HTTP binding in RFC 5985 is intended to reduce the HTTP feature
set that implementers need to support, not change it.  So any
compliant implementation should be fine.
