Thanks for jumping in, @octo - I meant to bump this topic today.
I think @c2yptic’s point is not that issuing MNDE to NFT holders would cause it MNDE to increase in value, merely that it would help stall the value dilution that is likely to take place during the time the NFT is locked (because of issuance through processes like liquidity mining)
I do think that it would be good to encourage long-term locking. Personally, I’m currently more inclined for the approach of periodically adding MNDE to the NFT, given that:
- This will have the net effect of a voting power increase (albeit gradually), and
- It would help counteract dilution through issuance.
Otherwise I’m not sure if I’d personally value the extra voting power that much over the flexibility of selling within 30 day notice, not to mention a potential dilution I can’t plan for.
Think of it this way: after a year, you not only enjoyed increased voting power, but you end up with more MNDE than you started with. 
What do folks you think?
