Subject   st: using heckman in combination with mi estimate

I have a multiply-imputed data set, where the number of imputations = 10 and where imputations are only performed on independent variables. I would like to run the heckman command on these data, using the mi estimate prefix. The heckman command is not a "supported command", but it is possible to force estimation using the cmdok option. My questions are these: Why isn't heckman a supported command? Are the results that I get when I force Stata to fit the model (using the cmdok option) valid? Or, is there some statistical reason why a Heckman-style selection procedure should not be used in a multiply-imputed data setting?
 
Any guidance on this matter would be much appreciated.
