Right now it's a bit abstract (I'm in more of a consultant role rather than service owner). I will be working with teams that currently have some other authZ setup who may be looking to migrate. For them it would be important to have tooling to do a migration. For simple schemas it may be better to do by hand, but if something complex emerges, it would be nice to have the option to write a translation script, which would be made a bit easier if I didn't have to write my own data model + serializer
