Should I take these responses to mean that you two are negative
about the approach of spending extra cycles to commands that can
leave the working tree in a "in the middle of doing something"

saying that it might be a good idea but "git explain" is a bad
name?

It seems like the point of this command is to show some state
information which would otherwise be hard to see. I think of 'git
status' as the way to look at the repository state. Perhaps we should
enhance the output of 'git status' to note things such as failed merges,
whether we're bisecting, in the middle of applying a patch series, etc.
There could be an optional verbosity switch to give "full explanations"
including recommended ways to deal with the situation.

Hardwiring the recommended workflow in the tools would reduce
chances of mistakes, but it could rob the flexibility from them
if we are not careful and forget to take into account some
useful combination of tools when adding such safety valves.

As long as the safety valves don't come up _routinely_ in certain
workflows, it seems OK to bypass them with a '-f' force switch. I
suspect the best way to figure out if such workflows are in use is to
put in the safety valves and see who complains; otherwise we're stuck
with brainstorming workflows and deciding whether they make sense.
