Usage of F macro in Serial.print in Pico?

[martinerk0]

Is using of F macro in Serial.print(F("looong string")); situations useful in Pico? UNO3 has 2kB of SRAM, but Pico has 264KB of SRAM and flash is supposed to be slower, although according to this not so much. On the other hand, you could wear out flash?

No, it's not useful and is a noop. Constant strings are left in flash and not copied into SRAM.
