Why does GDB currently still supports only the features of Fortran 77 language?

Nowadays, it is well known that Fortran 77 is a rather archaic and
outdated Language, and it has been replicated by more modern Fortran
versions, such as
Fortran 90/95/2003/2008, and so on.

But in the documentation corresponding to the latest version of GDB
[1], I noticed the following description, which surprised me quite a
lot:

```
15.4.6 Fortran

GDB can be used to debug programs written in Fortran, but it currently
supports only the features of Fortran 77 language.
```

Today in the 21st century, why does GDB currently still supports only
the features of Fortran 77 language?
