I like the idea of such a cap and the benefits that it brings in terms of broadcasting, team development and tactics, however our sport is already very physically demanding, with intense tournaments held over weekends or just a few days, and adding more physical expectations in the form of forcing players to play more often will also lead to more fatigue, and more injuries, which further compound one another and result in lower quality of games.
I also agree with Gearoid that it risks decreasing participation as players do not make the squads they want and can not financially afford to be registered with multiple clubs (think insurance, federation fees etc) or devote time to multiple clubs.
It may even have the opposite effect in that top clubs who are monopolising players will just end up entering more teams in national tournaments, as players will still prefer to train with the top players and coaches.

This essentially negates the role of the marker if they must always be a lunge/pivot and arm+disc length away from the thrower at all times. We won’t see and hand or foot blocks and experienced throwers will be able to throw around any mark that is that far away without trouble. Let’s not even talk about the fact that such a zone would make dump and reset throws extra easy as a reset handler could intentionally use this zone for a “safe space” where their defender can’t follow them for fear of the marker touching them and resetting the stall count.

Furthermore, it has other consequences that massively favour the offence. If I cut and catch a disc and at the same time my defender makes a clean but unsuccessful bid and lands on the floor in front of me, they are technically within that zone that they are not supposed to enter in your vision of the rules.

Making this a requirement is not only more inclusive, it is also much more practical, as it eliminates confusion about how many of each gender are currently on the line for each team. It ensures gender match-ups are correct, ensures gender pulls are correct and removes any cases of mistaking fmps for mmps and vice versa.
Perhaps this signal could even replace, or at least accompany, the raised hand/raised disc as a symbol of readiness that is currently required before the pull?

The only problem I have run into with this so far is that it has often created confusion when players ask for which gender majority is currently correct. I think this is due to people not being used to this concept and a lack of communication and tracking of ABBA by the teams, it would however be good to emphasize that the current gender majority should be shown on the sideline and teams must make an effort to keep track efficiently – i.e. reiterating what the current gender majority is at half time with the other team.
