The second half of your proposal I don't understand. If adb is in tcpip
mode, I believe a user should be able to specify a port number.

Agreed. We shouldn't switch the adb mode silently.

No, because you don't know what's the default one. IIUC, a user could
have enabled tcpip mode via

# adb tcpip 1234
