Is virtualjdbc extension deprecated, and what now?

On Hybris Help page there is a message on virtualjdb extension:

"Caution: This page refers to deprecated software. For further details, see Deprecation Status."

But when I page through all deprecation status pages from 6.0.0 to v1808, virtualjdbc is not mentioned anywhere. So no reason for deprecation and no migration plan.

So what is the recommended way to integrate with BI tools? Should we connect directly to database for this?
