just use mean and make a "n" count map then run r.univar to check that
the count map is all "1"s.

If there was a value option, it should be "most recent value". If the
data file has more that one point in the same cell, the later point
overwrites the earlier one.  It's possible to add that, but I'm not sure
if it is really needed. Can you think of a real-world example where
last-known value is wanted over mean? (or other stat)

A higher priority for me it letting r.in.xyz read a data stream from
stdin. Need for "most recent value" makes a little more sense to me
then.
