I second this.

I mainly use NPM on my internal ___domain but do have one or two things I expose externally, but locked down to specific IPs at the firewall level.

LE doesn't publish an IP range for allowlisting, so the DNS-01 challenge would be a no-brainer for me, except that my ___domain is hosted in DreamHost and, currently, not supported in NPM. So I have to periodically open port 80 or the world, which I'd really rather not do, just to get the certificate to renew.
