Are SqlGenerator implemented correctly?

I see that some features are not supported by the YugabyteDB. To achieve this, you override the support method return false, but there are also base classes that are defined in the ServiceLoader liquibase-core. Won't these classes also be loaded?

For example, your AlterSequenceGeneratorYugabyteDB class will be ignored and not applied.
