Yes. And yes.

The functionality (to handle active transactions during rebalance/splits)
was checked-in post-1.3.0. It is disabled currently, but should be enabled
in time for 2.0.0.

To clarify -
for 1.3.0, we still need the current recommendation for balance_switch
for 2.0.0, the recommendation is not needed since the functionality will be
enabled by default.

In the interim, a user will need to enable the functionality manually.

Regards,
Atanu
