Are there perhaps plans to remove this?

Before the reversed ChangeLogs, this option was useful,
but perhaps now removing it would really lower the traffic?

One would have to make a bunch of tests over 1-2 months, perhaps:

a) two with rsyncing every day
b) two with rsyncing 1/week, and perhaps even
c) two with rsyncing 1/month.

(where "two" means one with and onewithout --whole-file)
and add up the traffic.

I am not sure whether servers can be set up to implicitly assume
--whole-file to save possibly some resources needed to calculate
the checksums. This would give wrong results, of course.
In this case, it would be necessary for the tests to set up a
server with full support, locally. In the latter case, one could
also use historical webrsync data if they are available somewhere
which would mean that the tests could be done rather quickly...
