While there is sense in what you are saying you don't have to create the problem for yourself. Don't create situations where you rely on javascript in the first place.

Granted there are some cases where it is an acceptable decision to get yourself into the problem (because the advantages you gain by doing so are worth the costs). But often companies just create the problem for themselves for no good reason - they could have avoided becoming dependent on javascript to do stuff they didn't need to do in a way that broke (degraded un-gracefully) if javascript wasn't available.
