For instance, should we update \sloppy node to indicate that some people consider it a LaTeX taboo ?
Certainly not. I see nothing wrong with the description of \sloppy as it stands. error is detected earlier in the compilation. Sigh. Sure, but that's not a reason to say that the starred form or unstarred form is "better". Each form has its own positives and negatives. In general: Vincent, please refrain from inserting "taboos" or "judgements" or "opinions". If you're not sure, then don't insert it. Or do insert it if you want; eventually I'll get back to reviewing all these changes and I'll delete or reword it if I think it necessary. I don't have the energy or desire to debate every case with you. Best, Karl
