We are looking to add a few ways to do config validation, one of the ideas is around scriptlets (being able to run validation code inside the juju server in a sandboxed form).
Charms can certainly ignore/set Blocked for a config-changed value, but it doesn't help from the user then seeing 'juju config app' and still seeing the invalid value.
