Describe the request

Enable compiler warnings by default by changing the default value of the "Compiler warnings" preference.

🙂 Important information about potential problems in Arduino code will be visible to more Arduino IDE users.
🙂 Developers of shared Arduino projects will be encouraged to write warning-free code

Describe the current behavior

The default value of the "Compiler warnings" preference is "None"

🙁 Users might suffer from bugs that are difficult to troubleshoot without assistance from the compiler.
🙁 Developers of shared Arduino projects are not aware that their code produces warnings and so don't fix them. These warnings then make it more difficult for users of dependent projects who do enable warnings to differentiate the warnings in their own code from the warnings from the dependencies.

Additional context

Defaulting to not showing warnings is, overall, a bad thing for the ecosystem. Advanced users will have a hard time taking it seriously, when instead of owning the errors, the IDE sweeps them under the rug.
