New comment by leahneukirchen on void-packages repository https://github.com/void-linux/void-packages/issues/35457#issuecomment-1032794894 Comment: False, the command line editing feature is part of the "User Portability Utilities option", a noninteractive sh can very well be POSIX-compatible. (Also see `posh` for example.) I think we have enough better interactive shells packaged, so imo WONTFIX.
