In your case if the backend is static and RVs meet the need, the sheer ease of use as you describe is a terrific advantage for RVs. So use em! Nothing to feel embarrased about, pragmatic people make the world go round and have happy customers.

"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
