Snap folder end up being primed

Hi folks
I created a simple snap by running ‘snapcraft init’ and put a file in snap/plugin folder. The file would be a custom plugin and alike.
Here is how everything goes

After the snap package is generated, I can see snap folder is shipped into prime folder as well.
I’m not sure if it’s an expected behavior for a snap creation. But it looks like a bug of snapcraft. It’s a little bit annoying if a project contains a bunch of custom plugins, such as x-shell.py, x-apache.py and so on as we really don’t want to ship these files into final package.

i think that is handled in https://bugs.launchpad.net/snapcraft/+bug/1660890
(which is still open)

Yeah, this is supposed to be gated by an environment flag (but will most likely make its way to the snap when using launchpad builders).
