It would depend on the individual application.

Carbon is 32-bit, so you can build Carbon apps if you can build 32-bit apps.
You can't build 32-bit apps on Mojave, unless you sue the 10.13 or older SDK.

NSApplication is part of Cocoa. X11 apps are not written using Cocoa, so
setting NSPrincipalClass would not be appropriate.
The only way that I could imagine setting NSHighResolutionCapable to be
appropriate for an X11 app is if that X11 app is using GTK+ with Quartz.
