Actually, there IS.
Genuine Floyd Rose floating trems were designed to use 9 - 42 strings.
Other gauges can be used, but for the best performance, stability, intonation, and reliability, 9 -42 is the recommended string gauge.
Show me anywhere in documentation that Floyd Rose has ever said this. Even vintage ads and instructions from the first trems never list a "recommended string guage". Their main user, EVH, used lighter string(9-38 or something).
Based on your lack of knowledge of the single locking Floyd II from that other thread, you might want to do some research:
