As such the base declaration will typically deny connections to slot implementations which means a snap declaration from the store is required for your snap in order to allow plugging snaps to connect to it.
Gustavo, while the base and snap declarations are working as designed and with the intended purpose, it seems that there is a rough edge for slot implementation snap developers-- namely, it seems local installs of the snap block connections when we have something like this in the base declaration: foo: deny-connection: true deny-auto-connection: true The only way I can see for a slot implementation developer to work within the system as implemented is to a) upload to the store and request a snap declaration and b) upload snaps to edge so as to 'snap refresh --edge ...' to test their changes. Perhaps I am missing something... should --dangerous (or something else) try to do something smart here so Robert can develop the bluez snap locally before uploading to the store? Should we provide a way for the developer to sign a snap declaration for this sort of thing?
