Issue: https://cplusplus.github.io/LWG/issue3534

During the LWG prioritization poll it was suggested that this is a design change and should be seen by LEWG, maybe as a paper. Please take a look and let us know if you'd like the LWG issue closed, and a paper solicited to change it.

SG9 have looked at the issue. The preferences is not to have the concept as "// exposition only", Alexander have volunteered to explore the concept (and name) in a paper.
Forwarding to LEWG to make the final decision.
