Yes.
Let me quote in email something I just said in irc:
11:24 <Diziet> liuw: I think we need to decide what to do about Olaf's
complaint about vdev semantic regression.
11:25 <Diziet> I know it's late in the release but given that the best answer
is probably some per-vdev parameter to control the behaviour,
along George's lines, and the reason we're not adopting that
right away is compatibility pain: I'm tempted to suggest
reverting the original change for 4.7.
11:26 <Diziet> The conversation in the thread about how to fix the problem is
making progress but I am very uncomfortable with this amount of
detailed API design being done under release pressure.
11:27 <Diziet> Releases are about short-term thinking, which is harmful to API
design.
Ian.
