Correct. This is a misconfigured webserver, so the error is valid.

That's not quite correct AFAIK. Let's encrypt supports wildcard
certificates, so

  lmtx.pragma-ade.nl and

could be covered by the same certificate. And each certificate can
also cover multiple domains (SAN). So one certificate should be
enough for all abovementioned (sub)domains.

I totally agree on that one.

Certbot definitely supports wildcard certificates and AFAIK you can
just specify multiple domains with the ā€œ-dā€ option.
