Title says it all: Is ParameterizedFunctions.jl still deprecated in favor of ModelingToolkit.jl?
The disclaimer in the ParameterizedFunctions Git, “Note that this library is deprecated in favor of ModelingToolkit.jl,” is no longer there.

I plan to keep maintaining it as one of the DSLs that is on top of ModelingToolkit. I don’t think It will have as prominent of a spot in the DiffEq documentation as it once did (thought there might be a page linking to multiple such DSLs), but feel free to continue using it.
