As regards the backwards compatibility break here, I guess my take is that this change needs to happen some time and sooner is always going to be better than later. While we are still called flang-new and marked experimental I'm inclined to think we should just rip the band aid.

We could leave `-fno-fortran-main` in as deprecated but it won't actually do anything anymore, so that might just be confusing for users.
