These instances were detected by searching for files that include AK/Format.h, but don't match the regex: \\b(CheckedFormatString|critical_dmesgln|dbgln|dbgln_if|dmesgln|FormatBu ilder|__FormatIfSupported|FormatIfSupported|FormatParser|FormatString|Fo rmattable|Formatter|__format_value|HasFormatter|max_format_arguments|out |outln|set_debug_enabled|StandardFormatter|TypeErasedFormatParams|TypeEr asedParameter|VariadicFormatParams|v_critical_dmesgln|vdbgln|vdmesgln|vf ormat|vout|warn|warnln|warnln_if)\\b (Without the linebreaks.) This regex is pessimistic, so there might be more files that don't actually use any formatting functions. Observe that this revealed that Userland/Libraries/LibC/signal.cpp is missing an include. In theory, one might use LibCPP to detect things like this automatically, but let's do this one step after another.
