The type ratings are being handed out to more than international pilots already. 8710 forms are now being filled out for all first officer candidates at a regional airline that I'm working with.
By the way, your assertion that FO's under part 121 "exceed" the standards set under ICAO. I've seen a lot from all over the world and the FAA bunch are certainly no better than most, and in many cases the corners that can be cut for FO's under 121 and the lack of standardized testing for SIC's at most airlines that I've dealt with makes for some pretty scary folks at times.
