Like some interim replies, particularly Bart Butler, I thought we had a rough 
consensus and that it was approximately:

* MUST support 16KB chunks.
* SHOULD support 256K chunks, as these are common (Protonmail).
* MAY support larger up to the present very large size.
* MAY reject or error out on chunks larger than 16KB, but repeating 
ourselves, SHOULD support 256K.

I think this is fine. It covers what's requires for interoperability, it
makes prudent suggestions, and it allows people leeway if they know
they're the only one consuming their data.

If people like my original proposal, that's also fine with me (as would
be expected).
