How (if possible) can we get rid of SparseArrays and StaticArrays?

On 1.11 these are the 2 packages adding to the bulk of load times. From the code, I could see StaticArrays being used for CPU shared memory implementation. Not sure where SparseArrays are being used exactly. Is there a way we can move these 2 dependencies to extensions?

I can create a PR, but I need some help in figuring out where these packages are being used :sweat_smile: (and if at all this change is welcome)
