I would like the ability to change the display name on fields per custom form but keep the same list value for data governance and consistency.
One team calls the field "Market Segment" while another wants to ask the question "Which Market Segment are we targeting?" to better help their requesters. It's the same list value to maintain from an administrator perspective but helps the team get the right questions answered from their stakeholders.
With the new ability for Label and Name being separate, I don't see why it can't go one step further and allow the change on a per custom form for label. Similar to how a field can be required on one field and not on another.
