Well, I come down firmly....in the middle.
While I agreed the breakup and resulting chaos will drive many ex-SL systems to associate with the Renaissance Factor (in lieu of those dangerour neo-barbs from 'out there'. Include in that subtle actions by the MAlignment on the many SL worlds that they have infiltrated--not to the depth of the RF, mind you, but they have had centuries to work in and corrupt SL systems.
It is also indisputable that the RF must be able to defend and protect those systems, along with their own, from Warlords and any remmant of the ISLN that might try to oppose them. I imagine we'll begin seeing just how powerful those SDF's are by the next book.
The Lenny Det's and other Darius projects were originally for the 'next phase', IMHO--to impose on a now (relatively) peaceful galaxy the vision of the MAlignment. There will be opposition to this, based on humanity in general not being in favor of genetic modificaiton being imposed by their 'betters', and the Lenny Det's would have been there to crush any organized opposition to said imposition of the 'Great Genetic Evolution", in places like Maya or whatever was left of the PRH.
Well, that has been blown to Hades, and I still think the smart thing for the MAlignment would be to lie low for the next 50 years, but somehow I don't think they are going to do that. As the European nations found in August 1914, once mobilization has started, it is a very hard train to stop. And the Detweiler Plan, once started, will assume a logic andmovement of it's own.
So the Lenny Det's will not be used to enforce the will of the MALignment on a galaxy that is pretty much associated with the RF, but will have to be used to crush an already alert and very hostile opposition, who will also be actively recruiting new friends.
Interesting times, indeed.....
IMHO as always. YMMV.
