Eh to be fair other windows are pretty equally as absurd if you were to max out their object counts. In theory you can select a little over 500 footpaths (255 footpath surfaces and 255 legacy footpaths) and they'll all be in your footpath window... i can't even begin to comprehend that. So i don't think it's worth worrying about too much, as long as it still technically works it should be fine.
