REPL on MicroPython — was this always possible??

Mga 1 hour lang ako on the Pico W with Thonny. Connected via USB, opened the REPL, started typing Python directly into the running microcontroller. Read a sensor in real-time. No compile-upload cycle.

Software dev ako — sanay ako sa "save file, run python script, see result" loop. To be able to TYPE LIVE into a running embedded board feels like cheating.

Paano po kayo nasanay sa "compile, upload, hope it works" workflow when this kind of alternative exists? Or am I about to discover yung downsides ng MicroPython that everyone is too polite to bring up?
