I think at this remove it's likely not that worth worry about. If one 
were using semantic versioning, adding a new primitive would bump the 
minor version (so something like 1.41.0). However, that's not how pdfTeX 
versions work: the 'step' is .10 anyway, and various primitives have 
been added between 1.40.0 and the current release. So I was imagining 
that the pattern would continue.
