Can we somehow configure kotlinc (using Gradle DSL or compiler flag) to fail the build on unused variables/parameters/private functions (i.e. code that is 100% dead)? I only found allWarningsAsError but I don't want to make all warnings fail the build

AFK, but there's warning customization now, which lets you set specific warnings as errors. Just find the name for the warnings, and set the apt compiler flag

The compiler is able to report UNUSED_EXPRESSION, UNUSED_ANONYMOUS_PARAMETER and UNUSED_LAMBDA_EXPRESSION (these are names of diagnostics in the compiler suitable for -Xwarning-level CLI argument).
All other warnings about unused declarations come from IDE, not the compiler.
