based on this comment from slack

i though to have have such automated mechanism, would be a game changer for the ops template

that's why i came with a quick implementaiton of renovate
this bot will create PR for all argocd APP:kustomization and terraform .

i make a the default setting for the AUTOMERGE( but can be easily change in the JSON file , we can discuss about it if you want) (all config options are here

for me you can allow ALL to an AUTOmerge (in FF mode ) (fastforward merge lover here) .

because you provide a template on a one time based . so no risk to break anything on update in customer side. ( but maybe i'm wrong about it)

meanwhile,
you have to enable install the app trhough the github portal => https://github.com/apps/renovate

then i advise you to make firsly a silent config, like this you can check what is achieve by renovate.

then allow only repository where a config file is present.

more info about renovate here

edit: you can check created MR on my fork https://github.com/DrummyFloyd/gitops-template/pulls?q=is%3Apr+is%3Aclosed

to check how it's looked
