This doesn't handle DAEProblem?

Hmm... I didn't know that. Makes sense that SciMLBase can't make the same assumptions OrdinaryDiffEq did

I thought we talked about passing it?

Didn't you also mention having a trait and throwing an error message? Right now it takes a keyword argument and falls back to this if not provided.

That said I'm more than happy to remove this trait since solvers have to individually opt-in to doing initialization anyway.

Let's simplify and just make it required.

A lot of our tests still use codecov, apparently 😅 |

This is good to go. Downstream failures are BVDiffEq failing to precompile. |
This replaces
default_nlsolve
in OrdinaryDiffEq, and will have methods in NonlinearSolve which can then be leveraged by all libraries for initialization.Checklist
