BACKGROUND: We have a field called Dev Teams that is a multi-select field. It has been around a while and new teams have been created and older teams were disabled. For instance: Dev Team 1, Dev Team 2 were disabled when GUI Team, Database Team, etc were created.
CURRENT: We have about 20 teams in the list (though obviously the disabled ones don't show up in the dropdown).
QUESTION: What is the advantages/disadvantages of Deleting the unused teams vice Disabling them?
I see answers on how to, but nothing about impact of doing so.
