Again, I don't think *ever* is the right word here. E.g. the new OpenType 1.6 has recently defined new OS/2 version 4. While most font engines in use today do not know what it is and only can handle fields defined in OS/2 ver. 3, it's almost certain that future implementations will be updated to support ver. 4. 

I think that the situation with browser support for metadata will be very similar - if spec is updated, they will eventually update their implementations to support new spec version to show new fields. However, having predefined extension mechanism for metadata makes it less likely that we will need to update the spec any time soon.
