Namecheap has had its own host of issues like a few years back breaking hsts and causing tons of sites to break for quite a while and their response was basically oh well. That incident along made me move my domains off to porkbun.
Realistically you should never use the registrars dns to begin with. But you can set your own dns with porkbun, I have customs dns on all of my domains. I especially have been doing that since the Namecheap hsts issue. Can't trust any of them.
