The Flatpak is already packaged and works well. It just needs to be maintained from a person that joins the Inkscape community.
This would allow further improvements like Portal support and making the app official on Flathub.
Update: One might have been found!

EDIT:
Appimagelauncher, gearlever, AM, etc. Which is the same as a install wizard since it integrates the appimage into the system. AppImages do not need to be extracted into the system which is what windows install wizards do.
Appimages came before these tools, and the tools (forgot the name GearLever, AppimagePool is another one) came afterwards.
They are structurally better as they are external.
That verification is interesting. So it is another appimage, used to verify appimages? Are all Appimages using that, if not what percentage of the ones you know? And are tools like Gearlever enforcing or using that signature check?
Usually if the appimage has a github release with a zsync you have that verification.
I don’t use gearlever, as far as I know gearlever doesn’t even let you sandbox the appimage like AM does. I don’t think any of those forces signature verification besides AppImageUpdateTool and that’s because that’s part of the zsync update process.
Interesting, will look into this. The issue is of course that these tools are optional.
But if they work, they may fix nearly many issues. Some will remain, for example many proprietary apps dont use Github releases, while these may be especially targets of fakes.
