This is not a good idea, since it can break set ups that rely on the logistics area being a specific size. It would turn higher quality roboports from being a simple drop in replacement to one where you have to adjust the build to make sure that areas that are supposed to be disconnected stay that ...

I suggest to make roboport construction and logistic areas scale with quality, for now this is only possible with a mod that makes every quality a different entity which is confusing and having it in vanilla ...
