I'm sorry, I'm no TeX/ConTeXt guru and I really have no idea of how to
achieve this. I think now we need Hans' help.
I have indeed noticed that enclosing an operator between braces breaks
the spacing system. Try, for instance:
\startformula
\vec\nabla\cdot\vec u = 0
\stopformula
\startformula
\vec\nabla\cdot\vec u {=} 0
\stopformula
Unfortunately, using \phatom{=} results in the same broken spacing as
second formula.

Good point! Here's the fix (file updated on my website):

Now we got rid of the duplicate label warnings. I also added your
contribution to the usage example. Thank you.

David
