That would be fine! Although, I also don't think "best practices" would be something that changes every 6 months (maybe every 5 years), and being forced by the compiler to rewrite code to keep up with best practices is absolutely a good thing! I've been the lead on a fairly large Fortran project, and we make a point to run our test suite on as many compilers as possible, with the strictest flags to avoid any kind of "undefined" behavior (which is rarer in Fortran than in C). I believe it's the only way to ensure long term maintainability.
