There are dozens of -devel packages, which contain static libs only,
but don't provide a virtual -static package.
Many of them are OCaml (ocaml-*) and Haskell (ghc-*) packages.
The Haskell packaging guidelines contain a section that seems to suggest
that the packages need not provide a virtual -static package:
https://fedoraproject.org/wiki/Packaging:Haskell#Static_vs._Dynamic_Linking
What about OCaml?
https://fedoraproject.org/wiki/Packaging:OCaml
is not mentioning static libraries at all.
What other exceptions exist?
