OK, I wrote one. Please look at this:
This script uses pyquery, jquery based selector syntax. If you like jquery
selectors, then you will like it. It can add/delete/remove/update entities
Very cool! Something like that should be implemented as a virsh subcommand

True, but support also comes with docs, --help discoverability, no need to
know the XML syntax, and future proofing against XML changes. That said there
is definitely a need for both tools.
