So long as it can be locked out, I have no problem with it. But honestly, I think IBIS up to this point is better for stills usage than video.The simultaneous use of both lens and sensor IS can give video stabilization near the level of a professional gimble. That is massively powerful, even on large projects, because pro-gimbals are large and unwieldy and can't get into tight places.
A tool is a tool. It is only ego and lack of imagination that causes someone to ridicule and reject a new tool.
Up until recently AF could not be depended upon for video, so for predictable and professional results manual focus was the best option. At this point AF is good enough for my needs, so I use it. After many shots with weird warpy/jiggly artifacts, I can surmise that IBIS is still in the “not ready for prime time phase”. It maybe perfected for video use one day... but I would be surprised to see such a development this year.
