+# format - handled by black
+# locally-disabled - it spams too much
+# duplicate-code - unavoidable
+# cyclic-import - doesn't test if both import on load
+# abstract-class-little-used - prevents from setting right foundation
+# unused-argument - generic callbacks and setup methods create a lot of warnings
+# too-many-* - are not enforced for the sake of readability
+# too-few-* - same as too-many-*
+# abstract-method - with intro of async there are always methods missing
+# inconsistent-return-statements - doesn't handle raise
+# too-many-ancestors - it's too strict.
+# wrong-import-order - isort guards this
