Isn't it harmful to use db.DefaultContext now because this uses a context cache without request lifetime? db.DefaultContext is valid for the whole application lifetime. I try to replace #22491 but there db.DefaultContext would be used sometimes.

Here we use db.DefaultContext then there is no request level cache will be triggered. The context cache will be ignored here.
