Well, he hasn't played since 2015 so his playing days are over & therefore I have no more skin in the game, so to speak. I do feel that if we don't at least TRY to develop these U Sports qbs then why have 7 starters that have to be Canadian? Just get rid of the ratio & let all Americans play. Then watch the interest in the CFL start to wane especially with high school aged players who would probably decide not to play the sport as there'd be no way they could make a CFL team.
There has been talk of reducing Canadian starters to 5 with that idea getting a lot of blow back from fans. So, I'd suggest a lot of people actually do care if Canadian qbs do play. So, to answer your question, if my son didn't play qb then no, I'd probably not care. However, having a son playing qb NCAA D2 at SFU, I saw first hand the way the CFL ignores Canadian qbs like they don't even exist.
Since that time, the CFL & U Sports have a program where young qbs spend training camp with CFL teams. That wasn't really available back in the days my son played. Had it been, my son would have been ineligible to participate as it would have contravened the rules of the NCAA as he would have been considered a professional & not be allowed to play his senior year back then. U Sports has no such rule. Having said that though, I still think we should be developing young Canadian qbs if they have the potential to eventually start.
