A.11:6 - Consequences

Consequence	Benefit	Cost or boundary
Smaller durable vocabulary	FPF stays learnable and bridgeable across domains because already governed expressions do not become accidental U-kinds.	The comparison must show the best existing expression by value; retain a record or view when that answer is reused. Hand-waving about simplicity is not enough.
Better U-kind admissions	Complete admission requires the parsimony evidence: material loss, non-redundancy, action-facing contribution, boundary test, and reopen condition; these do not replace the other admission conditions.	Some attractive names remain local or dependent even when they are common in source traditions.
Clearer neighboring-pattern use	Readers know when to use E.24.UK, A.8, C.3, Part F naming, or a direct subject pattern.	The pattern supplies the parsimony finding; the governing admission test decides admission and Part F chooses the public name.
