Thanks for bringing this up, I personally really like the current
prepare-upload as it neatly integrates with my common habits.
But for wider acceptance such a higher level wrapper will feel more natural.

I did a few uploads with that, so far they all got detected well.
But I only used args, not mangle.

Out of that I have filed a few bugs, they will improve things but are
no total show stoppers
I'd like to have these being looked at:
- fails more visible https://bugs.launchpad.net/usd-importer/+bug/1942865
- help users more if args/mangle was forgotten
https://bugs.launchpad.net/usd-importer/+bug/1947138
- have less problems if non https:~/git....
