Re: [quicwg/base-drafts] Small clarification in 12.2 Coalescing Packets (#2900)

[MikkelFJ <[e-mail]>]

The Path Probe is abusing coalescing to ensure to get a long header
reflected via an invalid old handshake packet.

While I do not appreciate this design, everyone else seems to think it is a
great way to solve that problem.

If the old packet cannot not be skipped, this would not work. If the length
cannot be decoded due to other changes, this design needs to be revisited.

More likely though, the packet can be skipped, but some implementations
won’t, so path probing will be broken anyway.

I went back and double checked. I thought Length followed the packet
number, which is variable length, but it does seem to precede the field.
Perhaps all that does need to be done is to remove that sentence then.
