ESSENCE — stakeholders in section 8.1.4

Specification: Essence – Kernel and Language for Software Engineering Methods (ad/2013-02-01)

In defining stakeholders in section 8.1.4, the spec states "All stakeholders must be involved throughout the software engineering endeavor to support the team and ensure that an acceptable software system is produced." Keeping all stakeholders involved throughout any project is an ideal but in my experience, never happens, at least not in large projects. Is this a key factor in Essence or just highly desirable from a method/process perspective?

(From an evaluation comment by JD Baker.)

Saying "must" here is awfully prescriptive and, as indicated in the submitted issue, not always realistic. It is also stronger than the more detailed discussion on the Stakeholder alpha later in 9.2.2.1 would seem to support.
