There is no known hardware that has an speaker with no connection to it 
(and it would be a BIOS error if there was one), so it is not a priority 
(perhaps not even of interest) of the driver to support it.
Especially not as the option of using e g hdajackretask [1] to disable 
the speaker permanently is an easier and better way than starting to 
mess around with the connections and paths manually.

I understand that your intentions are good and that you want to help 
other users as well, and I don't want to scare you off, but in this case 
it seems to me like you have some private patches that makes the driver 
half broken, and then you want the official Linux kernel to fix up your 
private half broken scenario. Which doesn't really make sense.
