Depending on the upgrade of the software, we do not update our template every version. We'd been using our ArchiCAD13 template all the way up to 16. 17 was a big update with building materials, so we had to redo the template. 18 was another with the surfaces for cinerender, sadly, but for 19 we've pretty much re-used the 18 template, with very minor changes.
Work Environment is a different story, that one I have to recreate each version, to make sure I don't miss out on new features.
The attribute manager is a great tool to import settings. I ussually start with the standard template when there is a need for a whole new template and delete attributes from it, import the ones I want etc.
Consider having more than one template, depending on the scope/program of the project. We've got one for typical small residential work and one for larger buildings, this means both are relatively lean templates, not packed with a ton of things we do not need for the project.
