Comment (by Simon Charette):

 FWIW `functools.cached_property` adds a `RLock` acquisition overhead for
 thread safety which is not something needed by most internal Django's
 usage and third party ones from my personal experience.

 If we were to proceed with this patch we should measure the impact of this
 thread safety mechanism first and also document it.
