I agree with this, it's not the most user-friendly to place the plugins.
It also makes the cleaning logic more fragile. I suspect it was put here
originally because "parts" was already a directory used by snapcraft;
we'll have to give some thought as to where such things should go.

This I'm not so sure about. There are ways you can accomplish this
without specific snapcraft support (I see Loïc mentioned a few).
