Are we sure that the modified version of these that got ported to SciMLBase are actually exhaustive? I.e. regression that I caught with these tests in Catalyst still appear in...

I have modified this one, removing the SciMLBase related stuff, and also adding tests that static vectors can be used as input across all problem types. @AayushSabharwal

Haven't heard anything in a while, can we merge this @AayushSabharwal @ChrisRackauckas ?

So, there are a large number of cases where I do ```julia @test_broken false # Does not work for certain inputs, likely related to https://github.com/SciML/ModelingToolkit.jl/issues/2804. for u0 in u0_alts_vec, p...

It is meant as a reminder when you run the tests, it tells you that there are some broken tests and where (and links the issue). Do you want me...

@ChrisRackauckas I removed the stuff with the broken test, we can add them back later when they work. This should be good now. @AayushSabharwal do you have any last comments?

Actually, I should add that this is not as trivial as I first thought. E.g. if you have variables eliminated as observables from MTK, you might still want to provide...

I am not sure I follow? Here, `d`'s value is set to, by default, be whatever value X` has. If the value of X is updated so should the value...

Up until now the default value are the value of species/parameters at the beginning of the simulation (after which they can change). The the above example one would expect the...

I still think there is an issue here that can and should be solved before the creation of the integrator and simulation system initialization. I.e. ``` @variables t X(t) @parameters...
