Query: Not all I had hoped for

I understand how wonderful this item is for connecting certain GBA games to certain Cube games, but why doesn't it allow you to play GBA games on the big screen? Remember the Super Gameboy? I guess that's what I was hoping for. Hopefully, Nintendo is developing a Gameboy Advance driver to allow this to happen, but why release this item with only limited functionality? Some of the GBA games are great, I just get tired of squinting at the tiny non-backlit screen. I'm ready for F-Zero or Super Circuit on the TV.
