>“this is a pain for my specific and unusual use case”.Since when "being tight on storage space" is a "specific and unusual" case?
That's the whole marketing strategy of selling devices with small built-in storage (and no expandable storage, as iPhones do).
In any case, not wanting a ~150MB installation file to silently download and shit a ~4GB file all over your filesystem is not an unusual* case.
As sufficiently many people have pointed out.
