Hi Andrew,
For suggestion for new features or changes to existing features we ask that you submit them through the iDeas forum at
http://support.orcid.org/forums/175591. The forum allows for public comment and voting on the suggestion, and is how we try to funnel suggestions from the community into action items for development.
For this suggestion I can say that I'm concerned about identifiers not being visible since they are used for grouping works, and without them it's not clear why items are grouped together. That being said, we might be able to look at truncating identifiers, and with later releases of 2.0 we'll be changing how identifier types are set up so there may be a better solution for specific identifiers formats you are using, such as JWT.
