When user installs the software he should expect it to work with all
WebIDs in basic functionality, regardless how many additional syntaxes
it doesn't understand, sacrificing potential performance gains and

I haven't said that. That is wrong because there is a different option
which I advocate - have 1 simple syntax with simple semantics defined in
a spec, accounting for basic functionality, while welcoming conneg of
