@matt they're free to read my analysis, think "nah", and forget about it. I'm not particularly influential here, it just bothers me.
but the reason it bothers me is that the cost here is permanent irrelevance. is the point of a free software desktop to have direct, monarchical control of the development process of your compositor or whatever, or is it to provide *users* with a more accessible and open computing experience where they can have agency and control over their applications?
@glyph @matt over time things have moved in the direction you're suggesting. I think systemd and sway are pretty good examples. Systemd in particular implemented a lot of core functionality and stayed committed to their bit long enough almost every distro has continued to shrink their init script footprint.
The gtk/qt thing would probably also be taken care of best by shrinking the space of responsibility those toolkits take up rather than choosing between them.
