Because it will cause your file to move from the storage center to different offices. Trust me, you don't want your A-file to keep moving around especially if you are close to filing your I-485.
One of the reasons of the slow process is that staff sometimes forget to update the most recent location of the A-file in the automated tracking system.
Wait until you get approved and then start asking them for your document.
Hmm that makes sense now...thanks Assylum
