I read a lot of people debating about how "difficult" is maintaining 32-bit support, or if it adds more vector attacks to the system.
Don't fool yourself. Maintaining 32-bit support is "easy" (with all the technical issues we all know). This is simply a sales strategy.
It's the same strategy than disabling a glorified vnc (Sidecar) on three years "old" laptops. Sure you need a lot of horsepower to display a remote image in real time. Never done. Yeah.
Apple is taking the "appliance route". Your (my) Apple computers, your (my) Apple phones...are closed appliances (no ram upgrade, no battery upgrade, no significant OS upgrade). This appliance version do this, the next appliance version do that. Soon we'll see that they're no longer upgradeable computers, and we will be fine with it...sadly.
How is dropping 32-bit support a "sales strategy" for Apple? They haven't sold a 32-bit Mac since 2006. If anything, Apple is helping drive sales of other companies' software, and hurting the adoption of their own $0 operating system. For anyone with 32-bit software that won't run on Catalina, there's nothing you can buy from Apple which will help one bit.
