Режим позволяет перезапускать python тесты или интеграционные тесты на питон программы при внесении изменений в python файлы без перекомпиляции.
Сценарий:
- прогнали тесты
- внесли изменение в `library/python/func/__init__.py`
- перезапустили, смотрим на времена
На примере интеграционного devtools/ya/handlers/analyze_make/tests в codenv (base конфигурация).

В codenv в base конфигуарции (4cpu) невероятно долго идёт линковка. Тот же самый сценарий, но на mous (54cpu)

В новом режиме тест ожидаемо замедляется, так как все питон программы при каждом старте вынуждены читать файлы с фс (ещё через арк), а потом ещё и компилировать байткод, т.е. холодный запуск
