I believe this is correct given that the splat detection matches the one just above the new code,
however i'm not quite sure this makes sense overall. Does this make sense to do?
My basic thought is that we might be able to get less regressions by handling multiple
insertions of the same value into a vector if we form broadcasts+blend here,
as opposed to D105390, but i have not really thought this through,
and did not try implementing it yet.
