I disagree completely, and hadn't noticed the lack of dates. It would help me a lot to have that.
I don't see why the information would be turbulent at all, unless you tried to look thirty years ahead or something. Generally my pool of scientists and labs is relatively stable over the course of any given decade. Labs get added to the pool yes, but showing completion dates would just help me hand them out so that all parts of the big grand project get completed at the same time. That coupled with the fact that scientists often last a good fifty years and my developmental programs last ten at most means it would be the best thing ever for me.
