Yes, I think that's right.

Strictly speaking, I'm not sure that etex being a binary on its own is 
directly related to the Web2C version. I suspect it's a function of a 
separate thing, not indicated by any visible version numbers: the 
configuration used in building the programs for teTeX. But maybe that 
distinction isn't important for your purposes.
