It depends on the specific controller. For controllers which make
clear distinction between online and offline states for, say,
hierarchical config propagation, it could lead to buggy behavior if
the function body afterwards assume that the current node is online.
I don't know whether this is the case for the functions converted here
but even if so the patch needs to update the description.
