cz 457 Firing Pin

Found this. https://www.snipershide.com/shooting/threads/cz-457-firing-pin-profiling.7003216/ and

So my question is - was 22lr designed to hit the inside of the rim, instead of the entire rim? I wouldn't mind trying this, but am curious who has done this or whether it makes a difference. The thought is that CZ's design was a compromise since it is used for 22wmr and 17hmr. but for 22lr the reprofiling should make it better?
