Have you considered choosing labels that are themselves qualified
keywords with registered specs? That might feel like a workaround, but
I think it could get you most of what you’re looking for.
For example:
```
(s/def ::even-spec even?)
;= :user/even-spec
(s/def ::odd-spec odd?)
;= :user/odd-spec
(s/def ::label-even (s/spec ::even-spec))
;= :user/label-even
(s/def ::label-odd (s/spec ::odd-spec))
;= :user/label-odd
(s/conform (s/cat ::label-even ::even-spec, ::label-odd ::odd-spec) [2 3])
;= {:user/label-even 2, :user/label-odd 3}
(s/conform (s/cat ::label-odd ::even-spec) [2])
;= {:user/label-odd 2}
(s/valid? (s/keys) *1)
;= false
(s/explain (s/keys) *2)
; In: [:user/label-odd] val: 2 fails spec: :user/label-odd at:
[:user/label-odd] predicate: odd?
;= nil
```
