Fair point.

Trouble here is that if one of the sources goes missing, there's no rule 
to regenerate it, so an incremental build with a new autogenerated test 
won't work.

Maybe ditch the generator and keep the above rules to generate sources, 
except that they generate the sources in $(objpfx) instead of the source 
directory?
