Unifying `feta` and `fetaBraces` would therefore still allow selecting a different music font for your SystemStartBraces. What it would not directly allow is *also* changing the font that is used for `\markup \left-brace` and `\markup \right-brace`. Probably not a big problem. I'm not yet 100% sure that it will actually simplify things to unify feta and fetaBraces, but if it does, I think I'll submit it.
