bq. disabling v2 has no impact on the perf, you get the exact same numbers
You're right, the feature flag wasn't ever pushed down to PluginBag so there
was needless work being done both for JAX-RS and for the traditional
ApiBag-based v2 APIs when v2 was disabled. Working on a fix for that
[here|https://github.com/apache/solr/pull/1210].
