I can't think of any use case were modifying a SPC_NOMOD field would make sense. I think disallowing writes to these fields at database-load time would make sense.
Side-note: The Record Reference Manual says DTYP can NOT be modified (https://wiki-ext.aps.anl.gov/epics/index.php/RRM_3-14_dbCommon#Field_Summary_5) while dbCommon.dbd lists DTYP without "special(SPC_NOMOD)"? Am I missing something or is the Wiki wrong here?
