I tried to report an open calculus textbook from Rice University’s talking about relativistic mass as an error (It’s pretty well-established as a bad concept in physics education at this point as opposed to the momentum energy 4 vector) and they wouldn’t accept my feedback.
Yeah - I've seen "but it's on lists of most common misconceptions" closed wontfix. Errata are good for "author:oops,tnx", but work much less well for confused authors and bad calls, and not at all for judgment calls and alternate approaches. Some other mechanisms are needed.
