Really? I've been leaving them off, too. Especially because of this funny
comment in the upstream ghostscript:
/* Initialize the IDs allocated at startup. */
void
pdf_initialize_ids(gx_device_pdf * pdev)
{
...
/*
* Acrobat Distiller sets CreationDate and ModDate to the current
* date and time, rather than (for example) %%CreationDate from the
* PostScript file. We think this is wrong, but we do the same.
*/
{
... proceed to set CreationDate and ModDate to the current time.
}
}

That would look like this:
if (!getenv("GS_GENERATE_UUIDS") || strcmp(getenv("GS_GENERATE_UUIDS"), "0") ==
0 || strcmp(getenv("GS_GENERATE_UUIDS"), "no") == 0) ...

Okay :)
