The idea that a fork was designed to match a frame, while accurate, is also overblown.
Fork rake just isn't a big deal as replacement forks come in multiple common rakes.
And A-C length is certainly unique depending on the bike's intended use, but even that has some general ranges that largely make it a non-issue. 365-377mm A-C forks are still readily available in 1" steerer..
To each their own and all though.
