It's too keep disc games and digital games with identical parity.
This gen the relatively small installs you were used to were accessed in tandem with data being streamed off the disc. It allowed devs to get better graphics out of the console. However this trick obviously doesn't work with digital games since they don't have a disc to stream from. It resulted in digital versions of GTAV and other games having worse texture pop in.
To make digital games not have this problem, partial installs are now gone. Instead the game either streams just from disc or dumps all the data to your hard drive and streams from there.
