> require_serial:true is better choice than pass_filename: false as it can speed-up mypy for single file changes.
> Significant gains can be achieved for single file changes and no cache for all other files. This is majority of cases for our users who have pre-commits installed as hooks because most people change only few files and never run check with --all-files 
> When just one file is changed and no cache is built, the difference is drastic:
> require_serial: true (4s)
