I actually attempted the same before but didn't finish it for some reason.
I had a different approach in mind:

• add an optional method getSourceFile (maybe with a different name) to ParseConfigHost
  • if that method is present, use it to get the JsonSourceFile and without file system IO using ParseConfigHost#fileExists and ParseConfigHost#readFile
  • you don't need a new method on CompilerHost because you can simply reuse the existing getSourceFile and delegate to that method in parseConfigHostFromCompilerHostLike
  • createProgram already expects CompilerHost#getSourceFile to do some caching for config files of project references when updating an existing Program. otherwise it doesn't reuse the structure
• cache parsed and extended config on the JsonSourceFile (or actually TsconfigSourceFile)
  • so if ParseConfigHost#getSourceFile does caching, we can reuse the cached result and don't need to parse and extend configs again
  • no need to keep the different caches in sync

unfortunately that makes it impossible for API users to benefit from this caching.

@ajafff Yes its possible we could use getSourceFile to get the file (which cab be done in addition to this) but the reason we are caching the results of the parsing is because there is further work involved after getSourceFile that needs caching as welll esp since it calculates list of files and options to use etc which takes up lot of time when you have 800 projects.
