If no copyright assignment has happend, then the copyright still
belongs to the author
-- from the Git repository's LICENSE:  Copyright © Adam Nelson (2020)).
While possibly you might have made some small changes to flexvectors,
it seems that most code is preserved, so at most a ‘© FSF’ line could
be added (*), however, the copyright line ‘© Adam Nelson’ would need to
remain, otherwise the copyright lines are misleading.

(*) This assumes you did copyright assignment to the FSF, otherwise
‘© Vijay Marupudi’.

Furthermore, the license requires preserving existing copyright
notices:

The expat license is GPL compatible, but the expat license requires
preserving the license text:

> Permission is hereby granted [...]:
>

Here, ‘this permission notice’ seems to be the text of the expat
license.  But I'm not seeing this text in the srfi-214.scm of your
patch.

That would be up to the maintainers I suppose.
