It would be very useful to have the option to MERGE one User Group into another.

I haven't seen this feature yet, but it would satisfy the need to migrate an entire user group into another.

Use Case:

A new user group is created based upon a new privileged Semester or Yearly Membership group. Once that period is completed, that entire group is dumped back into the general membership pool. When the user-list becomes large, it becomes very unwieldy to singly change each individual's group membership. One might argue to simply change that new group's properties to mimic the "general" group, but that becomes unwieldy after only a few cycles/years, thus accumulating unnecessarily similar groups to manage.

Perhaps the feature could be called: "Group Dump"

Maybe this isn't a feature because it's very easy to do with a single query in the AdminCP SQL Toolbox?

UPDATE ibf_members SET mgroup=<newgroup> WHERE mgroup=<oldgroup>

Not everyone know SQL offhand, I only know a few commands and I can't even excute them without a lot of help.

Another way would be for the group [not each member] to be edited so that when a member makes their next post, they are promoted into a different group.

Yet another way is to delete the group. When you do this, it asks which group all the existing members should be moved into. As this request is based on a group no longer being needed, this would appear to meet the requestor's needs.
