Has anyone figured out a way to manage these automatically? In many cases they're delayed commits; one branch of the code is retained, and other paths are deleted, including switching code (eg "if <switch> then A else B end" ===> "A"). It seems easy, but in practice people do all kinds of weird things like caching flag values and random if/switch/etc. syntax. It's also cross-language in many applications.
