Reviewer comments:
Add brief section describing Http2Transport's stance on the properties enumerated in the WebTransport Overview. We can move this around later as necessary, but wanted to get the text in to document which optional properties are supported and which are not.
From the : We should enumerate the position that Http2Transport takes on each of these items. Specifically: No stream independenceNo partial reliabilityYes pooling supportNo connection mobility

Revised text:
5. <ins> The WebTransport framework I-D.vvv-webtransport-overview defines a set of optional transport properties that clients can use to determine the presence of features which might allow additional optimizations beyond the common set of properties available via all WebTransport protocols.  Below are details about support in Http2Transport for those properties. Http2Transport does not support stream independence, as HTTP/2 inherently has head of line blocking. Http2Transport does not support partial reliability, as HTTP/2 retransmits any lost data.  This means that any datagrams sent via Http2Transport will be retransmitted regardless of the preference of the application. Http2Transport supports pooling, as multiple transports using Http2Transport may share the same underlying HTTP/2 connection and therefore share a congestion controller and other transport context. Http2Transport does not support connection mobility, unless an underlying transport protocol that supports multipath or migration, such as MPTCP RFC7540, is used underneath HTTP/2 and TLS.  Without such support, Http2Transport connections cannot survive network transitions. 6. </ins> WebTransport Streams established by the CONNECT handshake and the WTHEADERS frame are expected to be protected with a TLS connection.
