So to answer some questions brought up,
.) What can you see on VuhDo that you can't see on default frames?
Clusters. GL seeing how many people are next to person X when you're deciding who in the party to PoH or in the raid to Holy Radiance. This by itself, can increase your healing by quite a bit. I don't care HOW good you are at watching people, but knowing who is the best person to start an AoE heal on? The most efficient way to do this is ONLY programmatically, not visually.
.) When I can see all the information I want on raid frames, why would I use an addon?
First, you can't see all the information you'd want as a healer. Second, assuming that you really were SO amazing that cluster finder really brought you very little, here are a few things you can do with VuhDo that you can't with default frames.
HoTs: You can have bars ticking down for multiple hots on the frames, which can instantly show you the time left on a HoT visually, versus having to grok numbers (even other people's hots). This helps considerably on classes for whom HoT's make or break their healing game, like Monks (particularly on 10 man, when you have to triage very quickly who to hit ReM on near the end of a TfT. EVERYONE has ReM on them, you need to hit ReM on the person with the lowest duration left - try figuring that out instantly using default frames).
Shields: VuhDo can quickly show you, not only who has shields, but what percentage of the max possible shield, on them. You see PW:S on three people in your raid, they are all at half health, who do you heal up first? With VuhDo it's simple, the one with the lowest shield. Can you see this in an instant with normal raid frames?
Customization: During certain high healing fights during progression, if someone gets a debuff, or possibly a buff, looking through all their debuffs on their frame is not always a great idea. With VuhDo, you can color the ENTIRE frame to any color you want based on conditions. So for example on Elegon I wanted to see who had the debuff? You could setup your VuhDo to turn the person's frame blue, or red, or brown, or whatever. On Malkorok, you can have the entire raid frame colored according to the strength of the shield the person has. If you can't see value in this as a healer, well, you should reconsider healing.
There is absolutely no question that raiding with VuhDo (maybe Grid, again, I don't know too much about it) is better than using default frames. Now is it 'possible' to do heroic raiding with just default frames? Sure. Is it a good idea? Well if you are really stuck in the past and don't want to let go of the default UI for nothing short of Heidi Klum in your bedroom? Then maybe. Otherwise, no.
