I think this is by design; interaction with the user should only happen after
the VimEnter event fires. :help input() reads:
NOTE: This function must not be used in a startup file, for
the versions that only run in GUI mode (e.g., the Win32 GUI).
Seems logical: How can you interact with the user when the user interface is
still in the process of initializing itself?
Instead of your workaround, I would recommend to be open for alternative flows.
I'm lacking a bit of context, but how about just detecting that Vundle hasn't
been set up, and :echoing "Vundle hasn't been setup yet; execute :VundleSetup to
do so, and close and restart Vim to apply the settings."
