They're surprisingly easy to read and I'd encourage any younger readers to have a look at ones that are appropriate to your field. You'll almost certainly learn something new and it's good to have a grasp of these fundamentals.
RFCs are generally easy to read but there’s a meaningful chasm between understanding the RFC and what actually gets implemented in practice.
(It seems extremely unlikely that the average non-junior engineer hasn’t opened up RFC 3339 or one of the HTTP caching RFCs, just for example.)
For example, you don't have to read the specific RFC to know the difference between 200, 400, and 500 status codes. Any layman's blog post (or literally just reading the response messages accompanying those codes in actual use) is enough knowledge to get you real far.
That said; if a senior dev isn't aware of 3339, the holiest of RFCs, then that's a problem.
Doubly so for the "meta" RFCs (eg 1925).
It's not "I tend to not want to work with people who name-drop RFCs", it's "people I don't want to work with tend to name-drop RFCs".
And PKI engineers are cool (and a lot smarter than me).
I think most people here can agree that seniors should be aware of standards for recording time. If you know you should write a date as "yyyy-MM-dd hh:mm:ss" (add precision or timezone information as required) then congratulations you are aware of the necessary standards.
I’d love to read it, but I don’t have the time.

Or as if the vibe-coder of today would've totally™ definitely© be the type of person to peruse the RFCs.
It's like saying the the proof of, say, Seifert-van Kampen theorem is "forgotten" because nowadays, my friend, people ask ChatGPT to write out solutions to their math homework.
