I use fedora on my work machine. It is a pain. But hey, freedom of choice has its drawbacks too.
But from your comments, the message I get is that you want to apply to become a maintainer in each and every Linux distribution's package repositories, both mainstream and niche? And apparently also create packages for some alternative package managers too? (e.g. mise, npm, Terra)
Your users on these platforms that you don't seem to understand, aren't expecting _you_ to package your own software, they want the maintainers of their distribution to package it, as they know the distribution, which you probably don't.
Large part of the point of using distributions like Debian and Ubuntu is exactly this, that there are people deeply familiar and knowledgable about the distribution itself, who package the software and apply any needed patches, or wrangle it into what's the standard for the distribution.
When something isn't packaged for these users but they feel like it's popular/useful enough to be, they'll open a request with their distribution for someone to maintain that, in the distribution itself, so everything is aligned. Even though they're not supposed to, some users will bother you and ask you to package it for them, which isn't correct and shouldn't be like that. They either package it themselves, or ask their distribution to do it for them, as the packaging shouldn't have anything to do with the developer of the software.
Distro maintainer curation is a godsend for security and reliability. Distro maintainers and people who work with them to get things packaged are heroes. But let’s not pretend that maintainer curation is something the average user trying to run a new piece of software cares about.
You somehow seem to be under the impression that all users are the same, which evidently they're not, then we wouldn't have many distributions.
Of course, most macOS and Windows users think exactly like how you outline. But the typical Debian, Ubuntu or Arch user don't think like that, as they typically understand what kind of environment and ecosystem they're in, where they don't expect every software developer to understand every distribution.

What in my comments gave you the impression that I'm trying to argue for this at all? Of course they don't care, otherwise they'd be maintainers themselves.
You said:

I don’t think that happens nearly often or quickly enough for most users to be satisfied. Hence why so much software is released through tertiary PPAs or .deb download links and so on.
