yes, this is how sideloading makes sure to always have a version bump,
even if you re-install the the package with changes without bumping your
version in package.yaml or snapcraft.yaml

this is due to the switch to system-image based images, there each
channel has per-architecture versions (which are currently in sync
everywhere due to pure luck), they will be synced up in the next release
when RPi2 goes official. the ubuntu-core used in RPi is identical to
what the beaglebone or amd64 images use as version 5.

i think just defining everything in /etc/network/interfaces.d/wlan0
should just work ...
