Should the tag terminal be renamed to terminal.app? I think this would help make it clear that the tag should only be used on questions regarding the macOS Terminal.app.
General command line questions not specific to the Terminal app should use command-line, as mentioned in the tag wiki excerpt for terminal:
questions narrowly about terminal.app alone should use this tag. Please consider using **command-line** for any question not specifically about the native terminal app
However it is still misused heavily. Other macOS app tags have the ‘.app’ extension, however this one doesn't.
Can the tag be renamed?
