Increase max order expiration

A number of users in the community have expressed frustrations with the current max order expiration of 8064 blocks (2 months). The purpose of this post is to discuss interest in increasing the max order expiration and if so, what should the max allowed be?

1.) Could increasing the max_expiration have any negative effects on the CP system (more orders to check for matches each block, etc)?

2.) What should the max_expiration be increased to? (48,384 blocks = 1 year)
