I'm kind of on the fence about this, I get that the naming is more consistent with unfix but it doesn't feel like a good enough reason to make a breaking change.

If we go ahead with this, let's at least make sure that we have a plan for percolating this up to DynamicPPL and Turing. Are we going to keep a deprecated implementation of decondition around like this?

Base.@deprecate decondition(model) uncondition(model)

On second thought, I like decondition better than uncondition. The reason is de- means "removal", but "un-" doesn't. Also Penny made a good point here, I am not sure the naming consistency is really worth it for a: (1) arguably worse name (2) breaking release from Turing&DPPL.

@yebai I would suggest just close the issue instead.
