Why remove the finch experiment here?

[vrk (LEFT CHROMIUM), 2014/08/07 01:25:00]

My thinking was that if we never wanted to turn on the finch experiment in M38
(which we wouldn't if we made M39 the min required version) then might as well
take it out of the binary entirely. But I'm fine to revert it - done.
