I tested it, with bug# 27593 it works and creates a reproducible groff.
So I pushed this set to core-updates; closing this bug report.
Phiew, finally almost done. There's one more patch for groff at bug# 27593 in
order to set the environment variable GS_GENERATE_UUIDS to "0".
Danny Milosavljevic (3):
gnu: ghostscript: Make "/ID" optional, depending on environment
variable.
gnu: ghostscript: Make XMP UUID headers optional, depending on
environment variable.
gnu: ghostscript: Make "/CreationDate", "/ModDate" optoinal, depending
on environment variable.
