Hello all,
As you may know, we currently have two levels of property constraints https://www.wikidata.org/wiki/Special:MyLanguage/Help:Property_constraints_portal: mandatory constraints and "normal" (non-mandatory) ones. In order to allow more flexibility and subtlety in constraints definition, we are going to introduce *a new constraint level, suggestion*. This way, editors can distinguish the really crucial constraint violations from the ones that only suggest additional edits that would be nice to make.
When setting up a constraint rule, you could define it as a suggestion by adding a qualifier to the constraint definition statement with the property constraint status (P2316) https://www.wikidata.org/wiki/Property:P2316 and the value suggestion constraint (Q62026391) https://www.wikidata.org/wiki/Q62026391.
The suggestion constraint would get a specific icon to make it clearly different from the mandatory and non-mandatory constraints. The current icons look like this:

The feature will be enabled on May 6th. Starting from this date, you will be able to define constraints as suggestions and they will be displayed as such for all logged-in users.
Please note that this is the first roll-out of the feature, some issues may appear. You are also very welcome to give feedback, if some things are not working as you wish they would, we can still fix them. In that case, feel free to ping me or write a comment in the related ticket https://phabricator.wikimedia.org/T204439.
Thanks to the people who made this request, this feature was suggested during one of the “pink pony session” at Wikimania and we hope that you will enjoy it!
Cheers,
