Yes, the problem is layers and protocols like coinjoins just split devs and users and there's too much to keep track of, and hence there's separate teams and some small in size that end up failing where others weren't even looking, while on monero all devs and all users only have to develop and worry about monero's only code, or separate implementations of the same thing like in rust, which creates room for even more security strategies I.e. differential fuzzing etc
