Speaking personally, I would put this slightly differently.  After
all, a codec with low implementation burdens may have very poor
bandwidth consumption characteristics, relatively inferior acoustic
range, or other problematic aspects which don't read on the
implementation burden.

As you note below, the overall problem is one of cost/benefit
analysis.  In the end, we need to find a way to avoid implementation
failure with a set of choices that represent the best overall
cost/benefit ratio in the contexts identified by our use cases.

Absolutely.
