I believe you on SAS practices, naturally.

In terms of Stata history, I think this could only be answered by Bill
Gould or another developer with a long memory. In the early days of
Stata, small changes such as minor new official commands were I think
often sparked by questions or ideas from users. Now the terrain has
shifted because it is easier to write what you want for oneself.
