Just to make this clear, I do not want to typedef structs as pointers.
I agree that it is confusing (although it has a good rationale for some
cases, eg. when structure size is dynamic).

I am not sure what do you mean. Each typedef, eg. vm_page_t would be a
structure, where vm_page_t * a pointer to it. No intention to typedef
non-structures in UVM.

Why not? Note that struct declarations wont be removed (cf. struct lwp
and lwp_t).
