Review Comment:
I agree the cost of the check is low, the main concern is clarity or reason
for implementation. Logging a warning seems like a good option, although it may
be difficult to describe it clearly and succinctly, perhaps something like
`ClassLoader conflict found: Managed Driver [{}] does not match Registered
Driver [{}]`.
