Similarly, if we end up with, f.e., both WebKit and Spidermonkey using
decNumber as our internal implementation of Decimal, does that count
as two interoperable implementations? It seems like we'd be at risk
of mostly testing that code against itself, so I would hope that we
look for such reuse cases when we're making sure that we actually have
usefully-distinct implementations of features to validate the spec.
