If there is no plan to enable this anywhere for years. This should not be
in the source today.

There should be at a minimum test for the parsing of the values.

Regarding testing the outcome itself...if the current infrastructure is
inadequate, you should look what can be done to fix that. Creating test
coverage is part of adding a feature, you should not dump code somewhere
and hope someone else will pick it up and ship it.

I would prefer you finish the feature before moving on the next one.
