I'm trying to upgrade @segment/analytics-next from 1.62.0 to 1.81.0 and it looks like in 1.81.0 NullAnalytics is not exported while it was in 1.62.0 (I'm using it in test).
I think it's a regression caused by b611746#diff-a9cd8d1cb9d3a4e4f87e0e1d7f7e93eef56d6656d644e7f349bc8e6d776a1f99 (export * to explicit export)
