The same here. decode_coding_iso2022 (which is also responsible for some ISO 8859 encodings) refers to Vstandard_translation_table_for_decode. The practical drawbacks *I* mentioned are basically the same with ISO 2022-7bit. (Disclaimer: I don't really understand ISO 2022. I am not even sure that this particular ISO standard specifies an encoding (character set + transfer encoding) or rather a standard *for* specifying encodings.) I see that ISO-2022-JP-2 is, thanks to Kenichi Handa, a registered IANA encoding. (But that is probably not the same as ISO 2022-7bit?) But that means only that you are not, strictly speaking, violating a standard if you use it in mail or news. In practise, however, I very much doubt that outside of Japan there are any editors, mail clients or news clients other than Emacs that are able to deal with it. I don't know whether being "8 bit clean" is still an issue for networking connections today. If it is, then ISO-2022-7bit might have an advantage for files in a CVS repository. But that's pretty much the only advantage in practise.
