I think this is a bug and not a feature request. Even the vanilla textures are growing in size and thus being able to add resource packs up to a resolution of 512, the server administrators should be able to add resource packs without any limitation of the file size. Why not implement a screen like suggested here? Even if not implementing the above suggestion, it is not much work to raise the limit! Even simply removing the limitation is not much work. And as you can see at MC-5238, that issue wasn't rejected.
