I looked into this while the US federal government was shut down, and it
turns out that it's more complicated than merely adding a notice in the
IERS file. One cannot simply translate the IERS file to the NIST file,
as the NIST file has information that the IERS file lacks, namely, the
last time that the data were changed. Although this could be worked
around, the workaround would add complexity that I'd rather avoid.
So any proposal should involve not only adding a liberal copyright
notice, but also changing the IERS file's data format, which would be a
bigger deal. I don't know whether the IERS would go along with that.
