awhile back I recall there being discussion of us making a migration tool to help folks with going from 0.12 modules to 0.13 style, basically making use of the code we're already using under the hood to convert the modules. did anything ever happen with that? are we still planning to do this? we've had some customers asking about it

The reason it's non-trivial to do automagically is that templating is tough—and sometimes literally impossible—to translate in a fully deterministic manner. We could at most do a "best effort" sort of thing, and perhaps more simply output the fully resolved action(s) and leave templating to the user.

A best effort tool would probably be still useful for customers to have as a starting point, as long as we make it clear that that’s what it is
