As a linguist, I say words are unimportant, until they are important. Sure, words have meanings, but they are never fixed, and they only derive meaning from the context in which they are used. Do we need new terminology? Maybe, maybe not. One thing you can count on, however, is even if you make a change now, it won't save you from unforeseen trouble down the line. Language is always evolving.

Having said that, while I support terminological changes, especially blacklist/whitelist, I do NOT support the use of `blocklist!! I'll allow deny-list, but introducing blocklist is a problem because its meaning is opaque. We already have block used in CSS, and block used in the Gutenberg project, which means blocklist introduces a third meaning for block. We don't need that, especially when we are being intentional about adjusting our nomenclature.
