So, you are proposing not to touch the existing code but do it for all new
code addition. I do not have any problem with that, except for the fact
that this would bloat new code, which is equally important, IMHO. Should
we bloat code to future proof coding error? If other folks think yes we
should (in the context of this code), then I¹d be more than happy to swap
the Œdefault¹ case with rest of the types of virDomainNetType.
