Currently Django lazily compiles some regular expressions such as those in
validators:
https://github.com/django/django/blob/54ea290e5bbd19d87bd8dba807738eeeaf01a362/django/core/validators.py#L17
This is to save on import time.
There are other import-time `re.compile` calls throughout the codebase,
these could be migrated to lazy regex compiles to save on their import
time:
