The question raised in the initial post is a reasonable one but coordination across all pocket billiard disciplines is an unrealistic goal to set.
While it tests many of the same skills as pool, blackball is a different sport played with different equipment and, for the most part, in a different location. Appleton, Selby, Shaw, Boyes, Melling et al, all have some of their roots in blackball.
Even for pool alone, date protection is starting to look like an impossible dream until such protection is regionalized (most likely by continent), but date protection that included pool, Chinese eight ball and blackball is absolutely inconceivable.
