Well, if history is any indicator, there will be an impact.
Granted, this is anecdotal, and second hand, but it is nonetheless topical.
Many years ago in the early 2000's, right before Enterprise aired, Paramount (pre-CBS involvement) engaged in a massive scorch-and-burn effort at conventions to crack down on fan-made merchandise. I attended Shore Leave outside of Baltimore on a Sunday one year and I noticed that the dealer tables were completely devoid of any starship resin kits or the usual racks of blueprints that I usually peruse to enlarge my collection. Anything of a fan-made pedigree was totally gone. I asked one of the vendors I knew from previous cons (Creation, etc.) what happened to all the stuff? He told me that, just the previous day, on Saturday, Paramount lawyers and cops came in and confiscated all the non-licensed memorabilia and even charged some vendors (whose tables dealt with that kind of thing more exclusively than others) with IP theft and copyright infringement. I believe there may have even been arrests. It was apparently like a drug sting for those who witnessed it. Many people ran from the room so they wouldn't get caught, reminiscent of a fraternity house getting busted for having a loud drunken party. It was apparently quite a spectacle. The guy I talked to still had some kits but they were hidden in unmarked boxes under the table so they weren't in plain sight. I wound up giving up trying to find anything new and interesting. Too many vendors were quite jumpy, didn't know me, and were afraid I was there to entrap them into selling something "illegally". Seriously, it was like I was trolling the alleys for a flippin' 8-ball or something! It was all positively surreal.
So there is precedent - don't know if it will happen again to this degree but they do seem to go in cycles, usually coinciding with the airing of a new addition to the franchise. The first being the mid-late-90's assault on fan-made websites (at the height of DS9's and Voyager's popularity), which eventually led to the "fair use" phenomenon. This one happened prematurely before Discovery was even announced thanks to AP's little games and the effects could be lasting.
