[GRASS5] Asking about feasibility of an addition to r.recode

I¹m involved in a project to develop a linkage between agent based modeling
platforms and GRASS. One item that seems will be very important is way to
change a group of cell values (i.e., cat values) given their xy coordinates.
I realize that it is possible to use the map calculator to create a new map
with 1 new cell changed. But AFAICT, there is no way to send a set of xy
values, along with new cat values for each xy pair and change cells in an
existing map or create a new map with the changed cells (and old values for
the rest of the cells). Markus suggested that I run this by the developers
list. I can make this a formal Œwish¹ if it helps.
