Thanks for bringing this up, and +1. In addition, config-get will
serialize int, float and bool using their usual Python repr ("1",
"1.0", and "True", respectively and without the quotes). I felt quite
tempted to suggest lowercasing bools, which was the original
intention, but by now it's not relevant really. In the end, I expect
quite a lot of charms to be able to switch to format 2 without any
changes.
