It would be sort of nice to get "hg import" to slurp up an mbox file,
but I suspect that it would incur a fair bit of bloat, even though
Python has nice code for handling folders and parsing email messages
already.

I've been thinking for a while that commands.py needs splitting into its
component atoms, which would make something like folder and email
parsing easier to stomach.
