this is good forethought. you are providing for potential developments.

yes. let them know that it is experimental and that they use it at their own

when the concensus is that the new feature is a valuable addition to the spec.

any experienced software developer knows that features under development by
a group may have design differences to resolve, and if we get independent
input from a variety of sources with all bearing in mind that the 'final'
implementation will most likely be a compromise of the various contributions.
build in the features, but make them easily removeable.
