We mostly just use `idf.py flash` for local development as well. It's fine. If you're doing *just* C/C++ changes (no lua changes) then `idf.py app-flash` just flashes the C/C++ firmware partition. In theory there should also be a magical incantation you can pass to flash just the C/C++ and Lua partitions, but we've never been bothered enough by flashing times to look into it too hard.

The on-board flash is rated for at least 100,000 cycles so durability shouldn't be an issue. If in a few decades you start seeing flash write failures then mail us your Tangara and we'll replace the chip :p
