It does if the max frame size goes back up to 64K. It was only reduced to artificially make continuations more likely, right?

As for common-case head of queue blocking, DATA frame payloads can still be limited to 16K if we like. Such a limit disparity also solves the padding granularity problem.

Again I’ll suggest that nobody gets “thrown off the bus” if the canonical translation to and from HTTP/1.1 uses an initial sequence of header blocks, with routing information going into the first block.
