NoSecurityIsolation Exceptions, or whitelist

[Simba98]

The NoSecurityIsolation=y makes a Sandbox to Application Compartment.
As far as I know, it is necessary for Msedgewebview2.exe, and many other trustable applications.

Is it a good idea that make NoSecurityIsolation a whitelist?
E.g. NoSecurityIsolationProcess=msedgewebview2.exe
Make Msedgewebview2.exe to Application Compartment but for the remaining process it is still in normal mode.

A similar idea can be extended to Hardened Box,
UseSecurityModeProcess=UNTrust.exe

And even for PrivacyMode.

1. Possible issues: even if an untrustable process is hardened limit, it still can load some evil code to the process which is trusted. So, it is still does not fully provided security.
2. Actually, for Adobe Creative CC, I can run it in Normal Box (Blue Box), but you know it embedded msedgeviewer, so that the edge can not be launched and the overall functionality is not satisfied. But If I switch to Green Box, Adobe seems like it can detect something outside my system, so it reports uninstall is needed. (I have Adobe outside of Sandbox).
