It's worth introspecting on why any given person might hesitate to feel that they can commit. This is almost always comes down to "maintainability"—websites are, like many computer-based endeavors, thought of as projects that have to be maintained. This is a failure of the native Web formats to appreciably make inroads as a viable alternative to traditional document formats like PDF and Word's .doc/.docx (or even the ODF black sheep). Many people involved with Web tech have difficulty themselves conceptualizing Web documents in these terms, which is unfortunate.
If you can be confident that you can, today, bang out something in LibreOffice, optionally export to PDF, and then dump the result at a stable URL, then you should feel similarly confident about HTML. Too many people have mental guardrails preventing them from grappling with the relevant tech in this way.
