There are two kinds of questions here: 1. What StataCorp might do; or should do, on which users can express opinions 2. What user programmers offer as extra programs. The _possibilities_ are defined by the fact that StataCorp publishes its data file formats and the _constraints_ by the extent to which old versions of Stata can not do everything that new versions can.

Or rather, I don't think this means much without a definition of "would not incur losses".
