LongDistanceFeatureQuery for DoublePoint

[Puneeth Bikkumanla]

Hello,
I was wondering if there is anything similar to the
LongDistanceFeatureQuery for DoublePoint. We are currently converting our
doubles into longs in order to use this feature but would like to switch
off of that. If nothing exists, are there any immediate challenges that
people foresee for implementing a "DoubleDistanceFeatureQuery" for
DoublePoint?
