I actually wonder if the shell interpreter or command-invocation code
(to cover automatic bootcmd?) shouldn't set this flag before invoking
every command, and clear it afterward? Or perhaps, a flag should be
added to commands that would benefit from this flag being set?

But this patch is probably a reasonable way to implement it in the first
place, so we don't add complex infra-structure if it turns out that
nothing else is going to require this feature.
