Mateusz, I'm glad you're thinking about how to discover a DOH service via
DHCP.  (I would recommend including DNS-over-TLS and RDNSS too.)

I don't think your goal conflicts with the existing text, so we can keep
the current draft as is.  The concept of trust is complex and depends on
the situation; the current text is a broad warning that we can easily
adjust and refine in future drafts.
