Well, strictly speaking there is more than one Fortran maintainer (see
the MAINTAINERS file).  However, I tend to act like *the* Fortran
maintainer - in the sense that I try to reply to GNATS bug reports,
gather bug fixes, etc.  The NAMELIST bug is described by:

Both patches are in the current CVS - the latter one only since
yesterday, so - yes - it hasn't have a lot of testing yet.
