We've been getting a lot of bitrate/codec questions that are on a very basic level. They are mostly concerning fundamentals of the topic. Do we want this kind of stuff here? Just asking..
If we do want one, we want one question to rule them all and all others should be closed as duplicate of that one. Bit rate particularly is highly content dependent and can't readily be addressed by this community outside of a general case.
Codecs might have a little bit more of a place, but again, I think one master community wiki question that we can update if an additional codec is asked about is all that is necessary.
I do think that questions about encoding are relevant to the final product of many aspects of sound, but I do think a one size fits all kind of answer is as far as we can reasonably take it.
