Firstly, so what you are saying, stop DCS developing new features and everything stands still until it's to your liking? OR the developers work to the current specifications of DCS and finish what they planned ...oh and advertise it as finished until DCS introduce new developments and the module is out of date ?
Modules and DCS are in continual development, as you can see changes are made on a weekly basis. As far as 'EA' is concerned, find another flight simulator that makes military aircraft to 'EA' level let alone so called finished !!
Take a look at the Mig21, they are still making changes to a 'finished' aircraft due to the advancement of DCS. Lastly, every piece of software will have some bugs, it's human error so you will be waiting for hell to freeze over if you are expecting ANY software to be in a 100% elusive state.
