I don't know what the Linux community's consensus on appimages are, but I wouldn't mind if people made more appimages because, for the few distros I've used, appimages just usually work.
AppImages are definitely convient to use. However the two issues I have with them are that there's no easy way to find them (eg flathub) and they're not automatically integrated with the DE. Requiring a tool that manages AppImages to make it easier.
