The Roman SIAF should be updated to the latest version (sending to @mfixstsci and @Witchblade101 directly as GitHub does not support attaching XML). The only changes are the addition of a new aperture for Roman PSS to use called "WFI_TILE". This new aperture shows the extent of the WFI that should be used when placing adjacent footprints next to each other in a nested pattern during a survey. WFI_TILE does not include the full extent of all of the detectors, and should likely not be used by most users.
