So you can have a library that uses these functions, without actually requiring a TH-capable compiler (e.g. it only provides functions based on these that a user _might_ use. You can also have (as it seems to be the case here) that a library uses the TemplateHaskell feature without actually using any of the symbols defined in the template-haskell library. Rule of thumb: If TemplateHaskell appears in the cabal file or a LANGUAGE pragma, then the Debian package ought to depend on the ghc-ghci virtual package.
