IIUC you can simply specify a dependency on `compat` and the package itself will
make sure only the necessary compatibility functions are loaded given the Emacs
version it's running in. So if you're running Emacs 28, nothing is loaded; if
you're running Emacs 27, `compat-28.1` is loaded to ensure packages written for
Emacs 28 can still be used; if you're running Emacs 26, both `compat-27.1` and
`compat-28.1` are loaded, etc.
