The following are the fields that are not yet properly dealt with by post-biblio fetch (as best I recall, anyway; I know these are the affected fields, but my notes were vague on exactly what goes wrong with each of them):
noindex gets unconditionally set to true
uploader gets set to the submitter of the post-biblio, in place of the original loader
identifier-access gets wiped
description gets set to the description fields (datafields 5xx) in the new record, which is correct *if* description had contained only what was in the old 5xx fields, but sometimes additional, non-MARC-derived, info is in the description field that should be kept, along with the new 5xx fields
