Hey @fossfreedom
The requirements for classic confinement are understood as this fits within the precedent of ubuntu-desktop-installer and uses the official template. The publisher (ubuntubudgie) has already been granted classic confinement for a similar request in the past (Classic Confinement Request: budgie-welcome).
As such, I have now gone ahead and granted classic confinement override for budgie-desktop-installer. This is now live.
Thanks
