I haven't seen any objections, so I moved on with restoring the old
behaviour.

Since I've restored the old behaviour, it makes sense to preserve the
old variable name.

Done. However, I don't want to make it private, since the helper could
be useful to other electric modes, which can enable or disable
features based on the operation mode.

Done.
Best,
