Another option would be to expose the setting to class libraries, so the
class libraries could pick between two implementation.

But I feel uneasy about adding this sort of feature, because it would
basically create another column in matrix testing (we would then have to
test everything against both configurations).

Am not sure that this extra source of potential errors is worth it at
this point.
