The reason for this is because if dns leak happens then isp can track you and can violate your privacy easily and can serve you targeted bs ads plus or throttle your speed and in DPI cases they can suspect you and can heavily restrict your activities or ban your ip too if using vpn and plus if proper dns is not configured correctly it directly opens risk for malware,phishing etc and as people soon wont be able to use best possible extension ublock origins because of Manifest v3 so dns or selfhosted dns server can only protect them from all bs ads and tracker of internet not just on browser but in every application they use So almost everything related to dns should be essential and must be encouraged to setup by any mean.
Rest your wish this was my honest opinion on that
