Is there a reason that ipv6 addresses are stored with uppercase letters in config ?
yes. See rfc4291, section 2.2, where all of the examples are in upper case. These examples caused people to prefer upper case notation for ipv6 address representation, although there was actually nothing in the document which actually mandated the use of upper case.
These recommendations have been updated in rfc5952, which requires (i.e. MUST) that all ipv6 addresses be represented in lower case. This document is standards track, so I guess Cisco is going to have to change at some stage. Given the current low levels of ipv6 deployment, sooner would be a lot less painful than later.
