Adding more event emitters

[leemind]

I would like to add a couple more event emitters - for example: customer_address_updated or customer_address_created . Can I just copy module updateCustomerAddress.ts into an extension and modify it - will that override the original OR would it be better to create a middleware function that just emits the event? Or is there a better way? (modify the source and a pull request!). I tried the first, but I can't get it to override, but maybe that is my misunderstandings of how the modules/extensions work.
