Not sure what percentage of your ISP users we represent, but our situation probably resembles other small/regional ISPs - started in the dialup era, small but support/MSP-heavy user base leaning towards commercial, sysadmin(s) working on contract.  Philosophically, we’d love to just flip a config bit in our two resolvers and offer both DNS over TLS and DoH and tout the privacy benefits to the users who care.  I suspect that this is probably more complex than that and involves spending precious admin time researching and vetting.  So my really short list:

- The 1-2 hour HOWTO-type document that covers config and monitoring (like is there a check_doh for nagios?)
- A 1 hour FAQ that has a good end-user pitch and something to address how wrapping any kind of TLS handshake and TCP around DNS does not make it noticeably slower for end users than good old UDP
