Allow separate edit and display titles for field

On sites where users manage content types themselves, I frequently see fields with titles that include explanatory text - "Proposal Summary (Be specific - 250 characters maximum)". As they see it, their users don't see or pay attention to help text, and only putting the instructions or descriptions into the boldfaced field title will do.

Which is fine, but then that becomes the "name" of the field in other contexts, particularly in display. And we end up writing views to display the nodes because the users want to customize the titles used in display.

It might be useful to be able to customize the field title as a configuration option for the entity display.

There is a Drupal 7 contributed module, Field formatter label, that looks like it does this. It's dependent on another contributed module, Field formatter settings, that has since been incorporated into core for Drupal 8.

So maybe it would be best to address this issue in a similar way. Depends on how common the need is, I suppose.
