Student loan debt relief

I claimed my child as a dependent on 2021 tax return.  As such, he is not eligible for the new student loan debt relief.  Is it reasonable to amend my 2021 tax return and take him off as a dependent, so that he can get the student loan debt relief?

 

He was full time student until May 2021, then lived with me. I did pay for most of his living expenses.  He did not have any earned income to report on a separately filed return. 

 

If it is acceptable to make the amendment, would I then have him file taxes with $0 income for the year 2021?

 

Thank you
