Any "information" or "quality" we can assign, maintain, or trust at an address, the greater the potential value in the right application, and the better overall network data we can give BTChris.
Keep exchange funds, officer funds / payments, and mined funds in separate wallets. They may be worth more to different services / merchants / etc.
For example, I could see these categories:
1. Proof Address - Address which only receives new coins - pools / solo miners / Officers.
2. Mint Address - Address which is 1 entity (person / company / etc) away from proof Address - Officer "contractors" / pool miners.
3. Near Mint Address - Address whose chain of custody is traceable to a Mint Address
4. Circulated Address - Address whose chain of custody is not traceable to a Mint Address - e.g., exchange bought funds
There's already enough mixing methods (e.g., coinjoin) if you want those, but there are also uses for not mixing. If you mix mined and exchange-bought funds in one address, you can't really prove which are which anymore, and you'd lose any additional "Mint condition" value in the future.
For example, it may be more valuable to prove "I mined these" than have no proof and have someone only buy at "circulated" prices...or someone offering services for only mint addresses / etc.
(Or, in political terms - officers are government employees union, miners are manufacturing / financial union, merchants are service employee / developers union - and if we can identify / assign / trace funds to their addresses, we can tailor services to specific members)
