It seems like the
lightning tag covers this topic well, and is more heavily used than
No. Lightning Experience is a very specific UI Framework. Lightning encompasses a wide variety of features, including
Lightning Process Builder,
Lightning Connect, and so on. LEX definitely deserves its own tag.
lightning has been tainted as an adjective tag, and I'm not sure it's easily fixable. Ideally, lightning should be aliased to lightning-experience, but then we'll have to keep fixing people that are tagging lightning with other tags, like service-console and lightning-components. We probably need some new tags, such as lightning-service-console, since there isn't feature parity with classic service-console, which in turn should be aliased to classic-service-console. I think we've got an inherent problem with tags as they exist today, and we should start monitoring them more closely, and setting examples by correcting tags. I've done a lot more tag edits in the past two weeks than I have in the past two years, and we've really only just begun. By not keeping on top of the Lightning situation as it developed, we've accumulated a ton of tagging debt that needs to be paid sooner or later.
