Biggest one off the top of my head is in the category of developer productivity (which i pay a lot for already), and specifically it lets me use my editor of choice (Helix/Kakoune currently) while getting powerful new features.
Huge hurdle, obviously, but my thought was an expanded set of LSP features from JetBrains, disconnected from their IDEs. They spend quite a bit of time and money on developing DX but it's all inaccessible to those of us who prefer different editors.
I'd pay a lot for these sorts of features that go above the existing FOSS LSP, while retaining more integration to the FOSS tooling we've come to know and love (like editors or choice).

There's more i'm positive, but i just woke up :)
