This might be a good solution to create tar files which is easy to do and easy to install for the user.  I think that creating packages is not that difficult either but I do not know for sure.   With few changes being implemented, making new builds semi-annually would most likely be sufficient.

I am still trying to understand appimage and flatpak usage but as far as I can tell, it only makes it easier for the user.  The developer/programmer still has to create the runtime.
