Dear ETS Users,

We recently have been looking into profiling the start up time of envisage based applications. During that investigation, one thing that stood out was the code used to check for methods decorated with the ``contributes_to`` decorator. We performed a GitHub search for users of this decorator and couldn’t find any. The typically used alternative approach to using the decorator is to define traits with ``contributes_to`` metadata. As a result, we are planning to remove the decorator in an upcoming envisage 6.0.0 release. See relevant issue and pull request here: https://github.com/enthought/envisage/issues/399 and https://github.com/enthought/envisage/pull/402. If you are currently using the ``contributes_to`` decorator we recommend migrating to use ``contributes_to`` metadata instead.
