Thanks! I'm in agreement with you, I don't like spending a lot of time on tooling if it isn't needed. I like only very simple tools, as I find complex ones inevitably add friction in the workflow and thus end up unused.
As the product and business matures, it's likely that you will need to spend more time to ensure that the business can keep up with the product.
As a PM, I make sure that we've had to do the same thing manually a number of times before we spend any engineering time on automating it, or setting up the tools so that a non-engineer can do it.
