It's really unfortunate that this is a part of the isolate state. Please explore
a slightly different approach. Make the InstallExtension family of functions
instance (instead of static) methods of Genesis and move all the extension state
tracking code there. To support the assert in serialize.cc a simple bool flag in
Bootstrapper (e.g. "have_installed_extensions") should be enough.
