I suggest we raise that limit to 2^63-1 bytes.

2^32 bytes only take a few seconds seconds at 100 Gbit, and files
larger than 2^32 are common as muck these days.

Raising the width of the window update itself is probably not needed,
as long as we squander the reserved bit on something else.

Never attribute to malice what can adequately be explained by incompetence.
