Sure... not sure where the best place to put it is, but how about 
something like:
-----
WARNING: The version of shp2pgsql installed by PostGIS 1.0 is not 
compatible with previous versions of PostGIS. If you are migrating from 
an earlier version(s) of PostGIS, and will be continuing to maintain 
databases using previous version(s) of PostGIS, you may wish to copy 
your pre-existing version of shp2pgsql to a different name (perhaps 
shp2pgsql_old) before it is overwritten by the PostGIS 1.0 installation. 
If you do not keep a copy of your pre-existing shp2pgsql, you will have 
difficulty loading data into your older PostGIS databases.

Now that I think a bit more about it, I don't know how many people this 
will really affect - I just now that it would affect us here at 
Refractions, as we have MANY PostGIS databases, of all different 
versions, spread accross several different servers. That said, it 
wouldn't be that painful to have to recompile an older shp2pgsql... but 
it's nice to give people some advance warning before you pull the old 
rug out from under them (even if they're supposed to be standing on the 
new rug).
