I don't believe there is a conflict. The main use case will be to
increase the output width of a shell command, in order not to loose
information. People will do this by setting a large value, say
1024. This will be used for both the synchronous and asynchronous case.

And then there's the use case to have a fixed output width for special
commands, in order to get a deterministic layout. This won't be applied
globally, neither for synchronous nor for asynchronous
`shell-command'. Rather, `shell-command-width' will be let-bound.

And we have the advantage, that synchronous `shell-command' behaves
consistently, for both the local and remote case.

So I don't see a problem.

Ahh, good catch. I've used @value{tramp} for this, as in the whole
tramp.texi. But this cannot work in @direntry, which is supposed to be
applied outside the document. I've changed it accordingly.

Best regards, Michael.
