Well, while one might say that I've changed my mind, I think it's more accurate 
to say that Alan has corrected a mistake on my part.

I had previously thought that it was forbidden to make things optional. Alan 
showed up on my doorstep the other day wondering why optionality wasn't pursued 
more thoroughly, and then he showed me some examples where something was made 
optional in a fairly precise manner. See for example the spec changes in this 


It seems plausible to investigate similar kinds of changes for RMI Activation.
