Maybe - I'm not pretending I've seen all possible configurations. Since
the idea I'm discussing is to just add some new models for several
laptops with subwoffers, ultimately it doesn't matter which pin has the
subwoofer connected, it just have to be correct pin for a given laptop
family (0x17 for mine, whatever corresponds to Master Mono for someone
else's etc).

Nope it doesn't. It is Lenovo Y550P with ALC272, and in my system, the
subwoofer is connected at pin 0x17. I'm not at it at the moment, but I
can send alsa-info.sh later if it is of any interest.
