Features to be removed from VCS

There's some features in vcs I plan to remove to ease working on it's absurdly big code. I haven't seen them used in the wild except long ago, plus in my samples and manuals by others. I'm calling for your opinion, however, to know for sure if I should actually remove them or not. Use the comments section below or, preferably, email me at outlyer@gmail.com.
