Virtually every GB set from the past 2-3 years included a 1.75u Control key option, and most extended-support retail sets do as well. Granite from PMK includes a 1.25u Caps Lock option, iirc. But, GB runners dropping support for the standard 1.75u Caps Lock key will not somehow result in the modern keyboard layout changing. People who care about their keyboard layouts and having correct legends are but a drop in the global bucket.
