(R interface, QGIS, ...)

Well I doubt they are used much. Especially as these are DB options.

upon reflection, one thing to consider is- are these used by addon C modules?

Looking through the addons svn I see 190 G_OPT_*, but those are limited to 
G_OPT_R_INPUT
G_OPT_R_INPUTS
G_OPT_R_OUTPUT
G_OPT_V_FIELD
G_OPT_V_INPUT
G_OPT_V_OUTPUT
G_OPT_V_TYPE


so ok?
