@lsytj0413 Adding the blocked status because, as discussed in related issue, the key property is used to compute a runtime defined key of instances of the definition.
IMHO, removing the mutual exclusiveness of id and key should be the object of the PR, not the removal of a (personally) critical field

[cdavernas]

As per comment, please re-add the key property, or drop that PR altogether.
As a rule of thumb, you should first have the go ahead from maintainers in a discussion or issue before doing a PR, that would save you the time invested, which I however thank you for 🥰
