It's just too weird to be public. Remove its properties from the wire protocol and from pluginrc. Instead, have all GParamSpecs' flags on the wire and in pluginrc, so we can use stuff like GIMP_PARAM_NO_VALIDATE. Port the remaining few places to GIMP_PROC_ARG_STRING(). I'm sure something is broken now wrt UTF-8 validation, will add tighter checks in the next commit.
