BDHU shouldn’t create a dip towards the hood per se; the levers should still support your weight, but this can vary depending on the shape of your bars and the brand/type of levers. And especially when it comes to gravel bars, which are more diverse in their shape/sizing, and BDHU doesn’t always hold as true..
The point of BDHU, as I understood it, was just making the transition from bar to hood appropriately smooth, and not using hood position – as jameso says – to not use them as a brace.
I also tend to find that BDHU solves the problem of “can’t reach the brake levers properly in the drops”. I’m of the opinion is that one reason people don’t like being in the drops, especially when they’re new to them, is the positioning of their levers; if the hoods are reaching for the sky, the drops become less usable.
Here’s my understanding, which might be wrong:
Then again: if you are more comfortable, who’s anyone to argue with that. BDHU is, I think, quite a subtle thing; the main thing it is designed to counter is having a completely flat transition from top of bar to top of hood, which is not as comfortable as it looks.
