It would be nice if the Koha database field borrowers.userid had a higher char limit than 75 characters. Increasingly, libraries are using organisational emails as a userid for single-sign-on. These email addresses cannot always be stored in the Koha borrowers.email field So the borrowers.userid has to be used for storing it. However, if an email address is long then it may not fit within the current 75 character limit of borrowers.userid.
We also have this use case as for authentication it needs to be in userid. We haven't run into the character limit (yet), but it seems a good idea to increase it. Please keep deleted_borrowers and borrower_modifications in mind :)

Yes, that is a good point that this change would need to happen on deleted_borrowers and borrower_modifications as well
