Well, it was mainly due to the discussions we have had about starting 
to use f-strings in OE-Core where RP has been reluctant to endorse it 
based on that it may cause problems when backporting code to Dunfell 
and Hardknott that still have older version of Python as minimum 
versions.

That said, create-spdx.bbclass is not likely to be backported to any 
older version of OE-Core so maybe it is ok to leave the use of 
f-strings as they were.
