This allows extensions to override the Flask.ensure_sync method and have the change apply to blueprints as well. Without this change it is possible for differing blueprints to have differing ensure_sync approaches depending on the extension used - which would likely result in event-loop blocking issues. This also allows blueprints to have a custom ensure_sync, although this is a by product rather than an expected use case. |

Flask
=====
Flask is a lightweight `WSGI`_ web application framework. It is designed
to make getting started quick and easy, with the ability to scale up to
complex applications. It began as a simple wrapper around `Werkzeug`_
and `Jinja`_ and has become one of the most popular Python web
application frameworks.
Flask offers suggestions, but doesn't enforce any dependencies or
project layout. It is up to the developer to choose the tools and
libraries they want to use. There are many extensions provided by the
community that make adding new functionality easy.
