We have some functionality in the old import classes than I'm 99% sure is unused
- adding tags to contacts (based on the 'Tags` column in the spreadsheet - no evidence of this having been used in living memory, no evidence of any bulk contact tag creates this year other than a bunch of 'Matching Gift Company' tags by @NNichols
- adding groups to contacts - based on `'Groups' column ditto - seems to have been maybe used or a good idea many years ago
- Adding relationships to contact based on the data in the spreadsheet column 'Target Contact ID' - part of 'Generic Individuals') (as opposed to the rules based additions where we add employer relationships of ?maybe? DAF relationships based on soft credits
- custom fields for organization (organization contact fields) - these are a bit more recent - ie there were discussed back here https://phabricator.wikimedia.org/T278892 but we no longer seem to import to organizations using the old methods and we removed the import organization check code a while back as unused - which is how I believe it was used
The only people to have used the old imports in 2024 are @NNichols @MDemosWMF & Ellen - so just looking for confirmation that there is nothing I'm missing here - mostly from @MDemosWMF since Benevity doesn't use these features
