Description
I just tried to create a custom type inheriting from SVector and create a custom indexing behavior (getindex(A::AbstractArray, p::MyPoint)).
In theory, one just needs to overload:
Base.to_indices(A::AbstractArray, p::Tuple{<: Point}) = round.(Int, p[1].x)
To make this work, but because StaticArrays overloads getindex(A::AbstractArray, x::SVector) this doesn't work anymore.
Is this just wrongly overloading the getindex interface, or was there a reason to overload getindex directly?

Research direction
Start by examining StaticArrays' getindex overload for AbstractArray and SVector, then compare it with Julia's Base.to_indices interface described in the issue. Determine whether custom Point indexing can coexist with the overload; done means the intended indexing behavior is clarified and covered by a focused regression test.
