I would not advocate dropping the command (and as you say StataCorp would not do so). What can be done is to move it to the status of - for- or -ivreg-. They are still there, just not documented, in their deprecated status.

The case for keeping -dprobit- is a case for backward

To maintain backward compatability, you should be very
careful about dropping a command. Basicly you should only
do so if it gives truely wrong results, and that is not the
case with -dprobit-. An altarnative to dropping the command
would be to depreciate it to an undocumented command (see:
- -help undocumented-). That may not be a bad idea, but than
again, I usually use -logit- rather than -probit- so I
wouldn't notice anyhow.
