Those billions of lines of existing code *are* the future of Fortran.

Every step taken toward deliberate incompatibility is another nail in
the coffin.

It sounds like you are saying Fortran is only alive now to keep all that archaic code useful. If that's all Fortran is to you, then it's already dead.

Besides, with a good archaic-to-modern Fortran converter, archaic humans can still write archaic code. My primary point is that there should be no need to worry about mixing archaic and modern code into the same source file, and an archaic-to-modern converter would keep all existing cond working indefinitely, without compiler develeopers having to deal with all the extra effort.

A nice sentiment. But it isn't really a significant problem in terms of holding back standardization progress and improvements to the language.
