But, perhaps, the problem might be that pragmas are not carried over? In my test the "importsOnly" version of the file is preserving two LANGUAGE pragmas that are necessary in order to parse the imports section (one of my tests uses PackageImports). Just a guess, but does 8.8.x now require more manual passing of the dynflags? This seems like a regression / bug to me but I'd be willing to workaround it if it is an intentional behaviour change.
