It seems to me that the same instructions:

 CREATE EXTENSION postgis;

would result in either having PostGIS with raster or PostGIS without
raster, depending on how the package was built.

Alse these instructions:

 ALTER EXTENSION postgis UPDATE;

would be ambiguous as to what the target version would be.

By having the same name "postgis" we're forced to have the same
control file, which in turn can only point to a single
"default_version".

So at the bare minimum, instructions for using postgis raster
should always add a step to make sure raster was included.
