I would think that web designers, and designers in general, would be happy with the flexibility to create their own thing rather than having something that pretty much looks like everything else.
The web used to have some consistencies, like <A> tags rendering as blue with an underline and always loaded a new page, but that's long since gone. Nowadays designers are free to make links look and work how they want.
I, personally, don't see the problem with lack of visual design consistency. I prefer to not have every app on my phone look the same.
