This API was simply an attractive nuisance as no code was ever developed
to actually process timing constraints (other than clock constraints
which use a different API).
While I do want to consider basic false path support, among other
things, in the near future; I plan for this to use a new API that
doesn't add complexity to the BaseCtx/Context monstrosity and that is
easier to use on the timing analysis side.
