In the following document the second a is much nearer placed to the V:
\starttext $V \mathbin{a} W \qquad V \mathbin{\mathbin{a}} W $ \stoptext
(in the second case an italic kern seems to be missing)
Can one avoid this side effect of nested \math-command? When building symbols it is not always easy to avoid such nestings. it becomes a chicken-egg issue because one can argue that a wrapped mathbin is no longer a pure bin and so ... it's again an indication that a wrong boundingbox (width) relying on always some kind of italic to fix it is a bad approach and recursively going into a bin (or whatever) node to see if there is a nucleus chactacer would be yet another 'configureble option' ... all is possible but the more we get of that
