What do you mean by warnings? If someone sets drizzle as connection
type, does it show a message on main screen explaining the problem
with the php drizzle extension?
If not, I think we should add an warning/explanation to the
Documentation or FAQ explaining the problem and suggesting to use the
mysql/mysqli connection type when connecting to a drizzle database,
until further notice. This to avoid that if someone tries to use the
'undocumented' drizzle connection type, they don't have a clue why.

Kind regards,
