The latter sounds like more appropriate as a lower-impact short-term
fix, so let's have that for now.

I however wonder if there are other settings that can be flipped
after we started talking to the helper to cause a similar issue,
and to prevent such breakages once and for all, we may have to
take the former route in the longer term.  But I think that can be
done later after the dust settles.

Thanks for a quick diagnosis.
