The idea is to silently block the package loading, and maybe load
configuration file with alternative definitions of commands which
could be used in the document. To suppress error messages, tex4ht
internal macro must be redefined and I am not sure whether it doesn't
break anything.  So it would require some testing :)

Maybe we could issue some warning message that the package is blocked,
error and compilation stop are unacceptable.
