Hello Daniel;

I'm not speaking for CRAN. I'm another maintainer whose current status 
page has a FAIL for that platform. But the FAIL notation is due at least 
in part to the fact that apparently the UCRT platform is less frequently 
run on the full CRAN package holdings. The note refers to a package that 
was updated a few days ago. The log file however has two other reports 
of failure relating to compiler warnings.

All the other platforms passed the newer versions. There is no mention 
of the UCRT platform at the CRAN Policies page: 

I'm waiting to see whether the aging fortran code generates warnings 
whenever the UCRT platform gets fired up again.
