Update:
OK, not entirely silent apparently.. but warnings are nearly invisible.
varchar(255) is a common type.. why is it no longer possible to create indexes on it?
The warning / error also seems to be inconsistent, in alter table convert charset it appears to be an error.
IMO it should always be an error.
