Subject: Cookie crumbling in QPACK?

Hi,

RFC7540<https://httpwg.org/specs/rfc7540.html#CompressCookie> allows crumbling cookies for compression efficiency with HPACK.  However, neither quic-http<https://quicwg.org/base-drafts/draft-ietf-quic-http.html> nor quic-qpack<https://quicwg.org/base-drafts/draft-ietf-quic-qpack.html> drafts mention cookies or crumbling.  Is it considered safe for a QPACK implementation to crumble cookies before compression and concatenate them after decompression?  If so, should the draft include clarification on this?

Thanks,

Bence
