This is something I'd love to see, the problem is that any "pay for features" model runs into serious legal issues:
- for American developers, many of them have provisions in their employment contracts that allow them to do unpaid open source work, but ban any kind of commercial (i.e. in exchange for money) activity. The fact that this reach into off-time by employers is possible is nuts anyway, but doesn't make the problem go away.
- as soon as any kind of money is involved, a lot of jurisdictions have provisions regarding warranties and liabilities - and these can be pretty enormous, see the log4j fallout. Some of these can be put aside by contracts, but nevertheless it's a legal minefield.
- some jurisdictions don't allow you to just take money in exchange for a project, it exposes developers to tax and social security liabilities. Even labeling such stuff as pure "donations" isn't safe if your tax auditor is particularly focused on nailing you.
- what to do if someone from a sanctioned country donates you money? What to do if you're European and get money from someone in Cuba (which is not sanctioned by the EU), but are employed by / work for American companies or intend to travel to the US?
- what to do if some arms manufacturer donates you / funds money for a project that could be used in weapons? Virtually all countries have some sort of equivalent to ITAR regulations that you really don't want to run afoul of.
