That is not a “hook”, that is an achievement. IMO, the primary advantage of SCEA is that it potentially narrows and helps shape your overall app process. If you get in, you do not need to apply to schools you rank below Yale unless you are chasing merit money. If you are rejected, you might want to readjust your range of what are safety, match and reaches. Also, if you might want to take another look at your essays if your GPA and tests scores were at or above the median for Yale. If you are deferred, your range may be correct, but you will probably want to include more matches in the RD round.
