Yes, I think an option should be a good starting point.  We could
document in its doc string that avoiding to load history makes remote
shell commands significantly faster.  And maybe the new option could
have a special value that disables history loading only for remote
commands.

TFH, I'm a bit surprised that the *Async Shell Command* buffer turns
on shell-mode, but then I almost never switch to that buffer.  I
understand the rationale, for those who do.
