All fair enough.

Even with Macaroon going away, however, Jamba seems to be going strong and provides the same benefit of extra macro length.

I do like the concept of using /click for organization. Especially since Jamba allows you to "name" the button so you can call:
/click JMB_TargetBlizzardsSpecialCaseStuff

which then is simply:
/target frost tomb
/target chaotic rift
/target guardian
/target TotemOfDeath1
