I don't think we should have any compile-time-options or a fixed limit. If we fix this, we should have named pickup groups that can have other attributes as well in the future, possibly using ast_objects. Using bitmaps and numeric matching was something useful when CPUs had less power than today, when people have dual core in their pockets. This patch is just a short-term patch, not the solution to the problem for me.
