It's a bit of a mess, but I think there are not too many packages
(potentially) affected by this particular problem:

% grep-aptavail -sPackage -FDepends elpa-f --and --not -FDepends elpa-s                                       
Package: elpa-jabber
Package: elpa-flx-ido
Package: flycheck-doc
Package: elpa-flycheck-package
Package: elpa-vimish-fold

Some alternate approaches (which are not obviously better to me, but
others might see something)

- add versioned depends on elpa-f to force it to upgrade to buster first

- special emacs load-path to those packages so they can find the old
  files s-el (that seems really ugly at first glance).
