Yes unless there was a reason this wasn't done in the first place.

If there is no need to use the special removal function (in case we add
insert_ressource) then yes. What about a pointer in
of_platform_populate()'s comment referring to the removal function?

It does actually the same thing as platform_device_add except the
"dynamic device id" and the resource insert if I remember correctly. If
you guys prefer the platdorm_device_add() path including
insert_ressource() I can try this.
