Description

For example too_many_arguments: it would be relevant to know the distribution of number of arguments among functions where this lint is being suppressed. The current default threshold in Clippy is 7. Is it the case that almost all suppression are using 8 arguments, or 8 or 9? Or is it a much wider distribution? That would be relevant for informing a choice of better default.

Similarly type_complexity: what is the distribution of actual complexity?

These 2 lints specifically are the top two most widely suppressed lints in Clippy. I think it's a reasonable takeaway that Clippy has gotten the default threshold wrong in both cases.

Contributor guide

Research direction
Investigate how noisy clippy currently gathers lint suppression data, then implement a command or function to generate a histogram displaying the distribution of argument counts or complexity values for specified configurable lints.
