'absolutely' - as an unqualified statement - is considerably
stronger than 'categorically' and 'IMNSHO'.

A situation where some but not all, lookups are recursively
nested, and potentially to different depths, may be supportable
in the code.

But 'IMNSHO' represents an administrative, user-interface and
user-education load that need not be taken on when many-to-one
flat mapping delivers the same result with fewer machine
resources and less risk of confusion.

Correct as far as the capability of the code.

But just because a thing *can be done* in a certain manner does
not necessarily make that the best course of action.

Take canine grooming habits, for instance..
