@aradi yes, excellent feedback and I agree. Being able to offer the old F77 interfaces (e.g., as global routines that internally `use` and call the modern routine version) would be good, that way the new library can be used as a drop-in replacement in existing codes, and they can later gradually migrate to the new interface if needed.

In general the modern version does not offer faster code. Just a maintained library.

And yes, you are right, there are no guarantees of maintenance, however the new code is on github now under fortran-lang, and anybody can contribute to it and help maintain it. For legacy codes that is often not true. Although both lapack and arpack-ng are already on github and one can contribute to them.
