Hello @Louis,
any progress on this, maybe? 
I do agree with @anon32808828 and others, and I explained my point of view in this post. It would actually be quite an important feature, this one.
Yes, Meta Box integration is on the roadmap, but currently nothing suggests it will be implemented any time soon.
So in the meantime and for those of us who need to use different solutions than ACF, the option to disable it, if not needed, would be really appreciated.
Cheers
