If you enjoy being a custodian no one is going to chastise you for that. As you have stated there are many nightmares to clean up and all teams need a person who wants to do the clean up.

This will keep you out of the bleeding edge feature/product space because you lack a honed skill in actually developing the app. Your skill is now to talk to an LLM and fix nightmare code, not work on new stuff that needs expertise.

Just food for thought.

I think writing code was never slow. Or atleast never the slowest part of the overall process.

Vibe coding might be fast, but thats only if you wish to pretend that coders deploy to production directly within minutes of writing code without product discussions, automated builds, CI/CD, code review, production testing, UAT, regression testing, security testing etc.

In reality when you factor in all these things, which are absolutely necessary if you don't want you product to break every new release and lose users permanently. You have to do the same drills as you always did.

To that end, unless you are building something very large, coding velocity is largely irrelevant.
