Why was this commented out in the first place?

It depends on capabilities being reported properly which wasn't the case so we
had to turn it off...

This seems like a valid check to me. If the application is asking for a
codec that isn't supported by hardware, should it be allowed to proceed?

It has been dead for quite some time, I don't know if ppl are reporting
properly. Turning it on might break which is something I would like to
avoid

It was broken so it's better to remain broken to avoid breaking things? TGIF.
