Thus, whether deprecation for them should be sent or not in a release cycle for removal in subsequent release. Logically, EXPERIMENTAL APIs are not part of stable APIs/ABIs and hence they don't really break an ABI. Thus, deprecation for them doesn't make sense. (or, as Luca noted on IRC, removing experimental is like de-deprecation :) ) On IRC, Luca pointed out that in one of the Tech Board meeting minutes [2], this was recorded but that too has slight ambiguity to it. Any thoughts on this? Or, was this documented somewhere other than [1]?
