Great, and no problem at all!
Actually in my case it is causing a bit of an issue with regards to performance. I stumbled upon the issue while troubleshooting recent performance issues on our site. See http://cl.ly/0V1r0U1s2L39 for an example of what we’re seeing – a large performance hit when hitting the get_all_auto_coupons() method (we have a lot of coupons so without the restriction check in place, processing takes a while).
Thanks!
