It is also practically speaking kind of worthless for actual numerics compared to, say, LAPACK.

People who grouse about Fortran have almost never used it for its intended purpose. It solves a problem, and does so very well. People who mention Julia, Python or Rust as replacements for Fortran simply do not know what they're talking about. You can do equivalent things in C++ or C, but you really shouldn't most of the time. Just as you shouldn't try to code up fancy data structures in Fortran.
