This might also be a good place to figure out if we can fix the compat issue of #1047

[ranocha]

Would it make sense to rename this to

Suggested change

	TrixiParticlesOrdinaryDiffEqExt = ["OrdinaryDiffEqSymplecticRK", "OrdinaryDiffEqCore"]
	TrixiParticlesOrdinaryDiffEqSymplecticRKExt = ["OrdinaryDiffEqSymplecticRK", "OrdinaryDiffEqCore"]

to avoid confusion on which package the extension depends?

[ranocha]

This would have to be renamed to TrixiParticlesOrdinaryDiffEqSymplecticRKExt accordingly.
