Urk, so it was a hack. Unfortunatly it seems something you can't really
change without changing the protocol.

So what are the options now? A GUC like so:

prepare_means_plan = [true|false]

So then a prepare will always parse straightaway, but you can choose
whether or not you want to plan straightaway or at bind time.

Would this be acceptable?

Have a nice day,
