Affiliations, You are who you know... Options

[Siege]

I was toying with the idea of package backgrounds -- a gang member picks this background and receives X benefits and Y penalties based on the character's affiliation with a particular gang.

How well would that work as an edge or flaw?

+1 Edge: Gang affiliation
The character is a known member of, or closely affiliated with, a particular street gang. This edge confers a -1 bonus when dealing with the character's gang chummers as well as dealing with gang-specific resources like fixers, street docs and so forth. [Just like organized crime (yaks, mafia, triads) have resources devoted exclusively to them, gangs will patronize certain resources moreso than others, particularly resources located within gang turf that wish to remain on good terms with the gang collective.]

Drawback: You receive a +1 penalty with rival gangs and their extended resources. Additionally, the character is likely to be hassled by rivals and will likely suffer a +1 penalty when dealing with LE agents that are aware of your affiliation.

Ideas? Needless mechanical complication?
