maninnet mean fT - exactly uniti-gain frequency. You can simply consider it as fT = gm/ 2pi(Cgs+Cgd). So fT depend from transistor size, bias current, and only gain factor - technology parametr. And gain factor increase in newest process But I don't know how use it (fT) in real circuit design.
It is laziness calculate. In pactice, designers not use fT, becase it is "too depend", subjective parameter with respect to sizing and biasing. If you actually need fT, calculate it yourselves,using formula above
it's better to do manually using formula, and it is for your purpose.
ft is important for high frequency circuits, but for cmos process, less important in designer's concern
