My opinion is that KDE project maintainers should aspire to get the projects into the hands of users in a way which makes it a useful tool for the user.  That means ensuring the projects are packaged and distributed and updated.  That's a big ask of course especially from volunteers but it would be the same of self hosted open source projects on Github or commercial proprietary projects, the difference is we have a community process where if you aren't sure how to achieve something there is probably other people who can help out.  When I first took over Umbrello 20 years ago I was surprised that as well as learning C++ and Qt I'd also need to know some artwork and how to make it translatable and follow UI design.  Actually making it available to users through app stores is another ask for sure but it's why I'd like that integrated into processes like the KDE Gear release service so projects can offload some of the work.  There seems to be minimal interest in this though which I worry keeps KDE projects back.
