If you have a lot of rules doing the same thing, bundles can be great, and I reccommend to take a look at this topic: Streamline work using Bundles
Also, for making the automations future proof and not dependant on individual contributors it might be good to look into service accounts
I should note these are features available to Enterprise (+) plans.
For other plans/situations it might be a solution to make a tech team, and add that team to the projects that have automations so you can ensure multiple people have access to the automations, and it is kept up to date with team membership.
