Do we have such a rule? If we have a subsection who's needed function
is return 1, I think that's a good indication that it's not appropriate
for a subsection and the end result is equivalent to bumping the main
driver vmstate version. It's convoluted to try to hide a one-way
upgrade in a subsection. Thanks,
Indeed, subsections are for data that is rarely needed so that there's
some chance (sometimes ~100%) of migration working seemlessly. In this
case it's either no-bump-and-live-with-the-consequences, or changing the
version id.
