I don't share your pessimism. I've mapped maxspeed=* quite a bit.
Compared to name=*, it's no harder to map, and it is of increasing
importance. I think we'll get far more than 8% of road names tagged in
the long-term future, and I think the same of maxspeed=*.
Well ... maybe not - since
I wasn't whining, nor was I suggesting that the project has no potential.
In fact, I think there are lots of good answers to the question how do you
use speed limit tags when only 8% of the roads are tagged with them? But I
don't think think longer-term is one of them.

whether the person who added the street to the map simply failed to
add the speed limit tag.

You don't need to bot anything, you can easily do this sort of thing in JOSM...

Did it prevent me from mapping when I discovered back in 2007 that the
map was almost blank? Did I think that the project had no potential,
could not become anywhere near suitable for routing? No, on the
contrary. And look at where we're now, only three years later!
Reasoning in half empty

tagged with a certain tag, it is sufficient that the tags are present
in the area you are interested
