It was my goal to at least not make it impossible.

Give the rapidly increasing volume of cryptographically whitened
data in headers, it might be a good idea to try to steer that data
towards a syntax which HPACKng/QUIC/whatever can recognize and
transmit as binary, to avoid the b64+compression detour.

Of course nothing prevents a compressor from speculatively looking
at a substring to see if it can be transmitted more efficiently by
un-b64'ing and then re-b64 it on the far side.

Somebody[tm] should really simulate that...
