Why? The connector properties already live in separate namespace from other connectors.

[ebyhr]

For consistency with other connectors. I suppose we use such prefixes regardless of namespace conflict.

LGTM % comment.

Consistency makes sense but personally I think moving in the less verbose direction is cleaner. I don't feel too strongly about it.

However your change matches the majority of connectors - trino-base-jdbc is the big one which doesn't use prefixes but almost everything else does.

Add a testLegacyConfigs?
