You’re welcome!
From your description here and in Request classic confinement review for LightBurn it does sound as though “strict” snap packaging could be made to work, but I know there’s a steep learning curve associated with snap packaging and you feel your efforts are better spent elsewhere. (FWIW there is no requirement to use CMake as you assert in the other thread.)
It is unfortunate that distributing on Linux is a fragmented landscape with .deb, .rpm, AppImage, FlatPak and Snap all being options. Visibility in the Snap Store could help visibility to Linux users, but I understand that is unlikely to be the main channel for discovery of your type of software.
