But it is. Because they're doing grab bag of different gimmicks depending on whether or not it fits the characters instead of mindlessly slapping it on everything for a "play pattern." Also yes SS does have a headmaster figure, and TLK did as well, which proves they can do headmasters whenever they please and not just because it has to be a linewide gimmick. Reusing the tooling for it isn't hard or expensive. Neither is including a targetmaster whenever they feel like it or doing a triple changer toy whenever they feel like it instead of doing the TR style of making every voyager a triple changer.
