Just because you can work with one monitor doesn’t mean multiple monitors isn’t more comfortable though. You can have multiple windows open at once, at full size, and glance between them freely. No need for them to share the limited real estate of a single monitor.
I run Sway on my laptop because it lets me take full advantage of my single monitor, but on my multi monitor desktop setup I use a regular floating DE.
The “make a fork” thing is part of the issue, I think. In general there’s this culture in the open source community that if you want a feature, you should implement it yourself and not expect the maintainers to implement it for you. And that’s good advice to some extent, it’s great to encourage more people to volunteer and it’s great to discourage entitlement.
But on the other hand, this is toxic because not everyone can contribute. Telling non-technical users to “make it yourself” is essentially telling them to fuck off. To use the house metaphor, people don’t usually need to design and renovate their houses on their own, because that’s not their skillset, and it’s unreasonable to expect that anyone who wants a house should become an architect.
Even among technical users, there are reasons they can’t contribute. Not everyone has time to contribute to FOSS, and that’s especially notable for non-programmers who would have to get comfortable with writing code and contributing in the first place.
