I mean that whenever a plugin is used on an image with the channel
size larger than the plugin can support, gimp should output a warning
message about loss of precision.  So I guess would adding a simple
check like this involve much much less work than the porting of a
plugin to GEGL?

Although I haven't got to read the code myself, I guess all we need to
do is to add a member in the plugin base class showing the type of
element it supports (8-bit int, 16-bit int, 32-bit int etc....) and
let the constructor of each plugin (both GEGL and non-GEGL) set it to
the correct value...........
