   This looks good - but if the #27251 is solid, I have strong preference for 
that one. Users don't read all the details in the documentation and they will 
expect it to "just work" . They don't even realise (and they should not) there 
is a lazy-proxy used. The whole taskflow API is there precisely to hide the 
implementation details (Xcom.push, Xcom.pull and the like) from the user, so 
this is entirely expected they have no idea about this detail. And since not 
many users read documentation, they will open an issue instead most likely 
(which we want to at least try to avoid).
   
   Another option (if we cannot make #27251 solid) will be to make a very 
explict error message when they try to push LazyXCom and point them to this 
documentation directly - then they will have a chance to read it and even if 
they copy&paste the error message in the issue, we will just close the issue 
and tell them to follow the advice they got.
