This one is somewhere in the murky ground between 'not a bug'/'by design' and 'not expected behaviour'.
The summary is that if you disable auto linking/url/iurl in the master bbcode options (under post options) but enable them in signatures, they still won't be parsed because the master list is disabled.
The design says that the list of sig bbc is simply what is *permitted* in a sig, not what will be parsed, but that's not necessarily either the most desirable behaviour nor the expected behaviour, and what would be ideal is to be able to switch between the two lists as needed. I don't think it'll be a *huge* performance hit since it can be done once per parse_bbc call rather than in the scary loops.
