Yeah that’s pretty much the point, but it’s a real world method to get work done , see the bounties here, it might be especially important if the developers make a mistake when prioritizing (which is expected because they are humans, if there are bugs in code there are bugs in priorities).
It’s open source, feel free to contribute. Throwing money to support a dev doesn’t entitle you to anything, let alone to be the arbitrator of their priorities. And this is the thinking that leads to dev burnout, and likely why Lemmy devs are not interested.
I don’t see a link for this, but found the github page for Mentions United.
