It's generally a lot easier to update games that don't use the templates, as opposed to updating those games that do use the templates. This is mostly due to the fact that the templates are always being updated, breaking compatibility with previous versions. On top of this the recent switch from C-Script to Lite-C has made porting old A5 template code to A7 stuff a very time consuming chore.

Luckily for me, I never use the templates. Personally I think they yield poor copy-cat style results.
