>the string through fixed bridge makes more stable in tuning. It allows one to easily use alternate tunings as the Stratocaster whammy would be complete useless in this scenario.

On the contrary, the lack of a floating bridge on the telecaster makes it utterly useless for playing a lot of songs and styles of playing that require it. Floating bridges have huge drawbacks to be sure (maintenance, tuning stability), but they aren't there for nothing.
