Whatever people write in emails is subject to misinterpretation. Emails 
need to be compact but then the intention does not always come across. 
If you continue reading my email, you will notice why I pointed this 
out: The problem is that we are now spending a lot of time on something 
(syntax changes) that was not even raised as an ISSUE beforehand. I did 
not say this is doomed, but I am not aware of anyone requesting syntax 
changes. The task that I was given was to clean up the metamodel, 
leading to proposal 3. Proposal 4 is now opening up many many other 
topics. I was hoping we could avoid these potential time sinks and rat 
holes, but I see that this isn't happening, and we are now even having 
metadiscussions. If that's where the group wants to spend time on, then 
let the fun begin... :)

Yes there are plenty of bad examples in this mailing list, 
unfortunately. I don't see what I did wrong in this particular instance
