Describe the request

As described here, the hardware_id was introduced as a workaround to help CLI consumers to detect a potential port change during the upload.

Once the feature is available and the CLI can provide the new port (if it has changed) after the upload, I propose eliminating the hardwareId from the gRPC API before the 1.0 release. I do not see why this should be exposed to the public. See the downstream change at arduino/arduino-ide#1913:

From here:

This PR has been created to support the "auto-reconnecting" to a board in DFU mode, which the R4 Minima goes into during upload and reset. The primary motivation was to make IDE2 compatible with the Uno R4 board.

Related API:

arduino-cli/rpc/cc/arduino/cli/commands/v1/port.proto

Lines 34 to 35 in 62bb4c4

	// The hardware ID (serial number) of the board attached to the port
	string hardware_id = 6;

I can open a separate issue if it's needed.
