How is this meant to work for classic snaps?

[Kedstar99]

Whilst working on vscode for hacktoberfest, I noticed that the recommended approach was to add this code into stage.

gnome:
plugin: nil
build-packages:
- software-properties-common
override-pull: |
add-apt-repository -y ppa:ubuntu-desktop/gnome-3-26
apt -y update

That and it requires a specific launcher that gets bundled with the given application.

From what I have read so far, classic snaps are unable to use this repo or it's launchers due to the content interface being unable to connect to gnome plugins for valid security reasons.

Is there an elegant solution planned to solve this? The current mechanism prevents classic snaps which requires Gnome software from being upgraded to use core18 or using the newly updated gnome-snaps which I assume have some snap specific fixes.
