As long as we provide a backwards-compatible setting, I don't believe
this change will be a huge deal. The problem with the implicit-casts
business was that there was no reasonable way to provide a control
switch --- the catalog entries were either there or not :-(. So far
as I can tell at the moment, there won't be any large technical cost
to providing a backwards-compatible option for this plpgsql change.
