The problem with Chrome not having such an option is not just limited to startup time when restoring a session. Having too many open tabs causes the resource consumption to go through the roof (especially RAM and CPU cycles). I can easily have several hundreds of tabs in Firefox (in combination with tab groups) because I usually use different small subsets of tabs during my sessions so the resource usage is quite manageable.

I've said it times and again: Chrome is optimized for a single use case (i.e. few tab users) at which it excels but tends to break down quickly once you leave its comfort zone, unless you have a fairly powerful system. Maybe the project leader nudge, nudge could divert some resources to make Chrome scale better. ;-)
