I've never needed a 22nd fret either, but for years people ridiculed Fenders because they only had 21 frets while Gibsons had 22, as if that was some kind of advantage. I mean, can't you stretch the string a half-step on the 21st fret and get the same thing? You're certainly not playing chords up there. So, they finally said "Fine! Dammit!" and started building them with 22 frets. Now we've got to deal with fretboards interfering with pickguards. Then, of course, some guys had to have 24 frets because, well, just because. So, not to be left out, Warmoth offers it, too. Gotta give the people what they want.
It would be interesting to know what percentage of their necks are ordered with the 24 fret extension. I can't imagine it being useful. But then, look at Les Pauls. They're pretty useless above the 16th fret or so unless you have some kind of freakish hands or enjoy carpal tunnel syndrome. So, apparently there are a lot of freakish hands or masochists out there <grin>
