Is there a plan to fix the use of document number in the Error panel for validation rules?

Summary:

Error panel shows document number instead of sequence number leading to confusion when reviewing output from Validation Rules.

My research shows that this was a bug (31913636) introduced in 20C, I have also found idea 662515 which aims to address the issue with more flexibility.

Is their a plan to address the bug in the near future?

What is the recommended workaround to this problem?

Is it a combination of the suppression of the row number (via css) in the Error Panel and use of BML to add _sequence_number to the validation rule message? We are a European wide implementation so managing message translations becomes another overhead if we go via BML.
