What makes that a worse option? Most of the patterns don't have constraints and don't want to deal with that. See the ugliness I had to play with the enabled attribute in the earlier version of the patch to deal properly with the constraints. Many of them actually don't create any pseudos, just want to be matched only before reload, split there and not match afterwards.
