Thank you for the proposal. However, we are not able to accept it:
a) Every pull request, as the one above, involves too large overhead of work comparing to the value it brings to the system.
b) The message is too specific, shows internals of class and in requires fixing it in many cases of changes to this method or property.
c) The message says nothing about same specific things - _store, _isSingleStore, etc. - thus it is still incomplete.

Closing.
