FF[4] supports board sizes up to 52x52, by differentiating between lower and upper case vertices. Would it be beneficial to change GTP's current case-insensitive format to take advantage of this?
Not in my opinion. Extremely few games are played on larger boards than 19x19 and most of those are probably on 21x21. Adding support for sizes 27x27 to 52x52 but not for arbitrary sizes would be fairly pointless and is not worth introducing case sensitivity.
