This is less exciting to me, but probably safer. It does work, as a model. Adding some extra "candy" techs and maybe some other techs to specialize or otherwise improve things would be a nice option.
Is hacking coming back? The hacking options we have in Classic right now both fix some issues (ie: having to guard a fab that's just in an undefendable position) and provide a lot of neat things to do (design backup corruption, steaing designs, hacking ARS, etc). Not having all that stuff but retaining the other stuff would kind of feel like a step backwards to me, and the document kind of alludes to that by talking about how Keith already fixed some of the problems.
They're only "fixed" if the tools to fix them stick around, of course. If we go that way, I'm okay with that. The tech side is less interesting than the original proposal, but I love hacking and can certainly see what's being proposed now working well (with hacking).
