People have likely already been mirroring it quietly for years.

IRL, "scanparties" used to be a thing if you were in the "bookz scene" around the turn of the century. (Where you and a small group of others go to a public library, hit the limits of your library cards and often clear out entire sections of shelves focused around a particular topic, meet someplace to scan/"cam" everything you borrowed as quickly as you can for processing and uploading in the near future, then return them all within a few days, and repeat this until you get bored or have other things to do.)

I used to do that with blurays when I was uploading releases to TPB.
