Review comment:
Is this the right test to do? Should we rather ask the Master if this is
an active Region? Asking the FS could be racy? E.g. something like
maser.getAM.getRegionStates().isRegionInRegionStates... It takes HRI which you
might not have so you might need to add a version that takes encoded region
name?
