---------------------------------------
Hello [~crizzis],
I think any change in behavior should be opt-in which your proposal seems to
offer.
This feature might trickle in a few interesting places and we should consider
if we need offer a ComparableBuilder that falls back on equals() has a backstop
or bake in the Comparable option differently. This needs more think and
experimenting.

> Project: Commons Lang
> Issue Type: Improvement
> Reporter: Krzysztof Sierszeń
> Priority: Minor

> ATM all fields seem to be compared using equals in
> `org.apache.commons.lang3.builder.ReflectionDiffBuilder`.
> However, comparing BigDecimals using compareTo (i.e. ignoring precision) is
> such a common use case, that I feel this could be a configuration option for
> `ReflectionDiffBuilder`.
> I can also think of two more generic alternatives:
> # a config option like `.usingComparatorForType(Class<T>, Comparator<? super
> T>)`
> # compare *all* `Comparable` types using `compareTo` rather than `equals`
> (potentially also configurable via an option like
> `.preferCompareToOverEquals(bool)`
