Magic likes being dramatic. That's tricky to combine with secrecy in the era of the Internet when a single event can be broadcast worldwide in moments. Yes, magic could make it so that all spells interfere with cameras, but that's a rather crude patch. Someone would work around it eventually, and the interference itself could draw attention.

I expect that will be one of the "minimal changes" it makes. Making it require a lot more effort and/or special circumstances to become a magic user would easily accomplish magic's goal of staying rare even after a full public reveal.
