Holzfäller was about the story of a certain Wolf. The theming effort required to bridge the gap between "Holzfäller" and the Big Bad Wolf story is trivial. It's a direct reference to one of the biggest characters (and one of the most German characters) in the whole story. I think you're selling BGW short if you don't think they could communicate that Der Holzfäller is hunting the Big Bad Wolf. Hell, compare that to the likes of Verbolten. Verbolten is themed to a German autobahn tour company whose incestuous sibling owners have been investigating an array of mysterious happenings in the Black Forest.
Despite Verbolten's name being only tangentially related to the actual story, the lore was easily communicated by the attraction's queue when it opened. This idea that the name of a coaster has to directly include a word stating the core theme or no one will understand what is happening is preposterous.
It's also just patently absurd to critique a fansite for not magically managing to pick a name that fits BGW marketing's arbitrary requirements 9 months ahead of an announcement. Plus, if I were running a bespoke coaster naming consulting firm for BGW, trust me, I'd be cashing a paycheck.
Anyway, I have no idea why you keep circling back to criticize a codename for a leaked coaster project from last year. It seems like you're just taking pot shots for the hell of it.
