I know this would be an extra spending for a lot of people, but a possible way around this entire situation is using End of Reality server hosting.
Our server we have with them still has the R6 patch, and has options to install from R5 up to R7 at will. If a few people picked up servers, it wouldn't be that difficult to rotate out and at least finish up the first round of matches.
