Given the history of the issue, I think that it's unlikely that this will happen. Your message hasn't generated a cascade of discussion. And, of course, even if you had provoked a discussion, R Core would have to agree that this kind of change is desirable. > > > (I recall, BTW, the sometimes acrimonious previous discussion of this > > issue.) > I could not find this discussion, do you have any pointer? Sorry. I don't recall when the discussion took place and failed to find it just now when I tried to locate it in the R email list archives. > > Anyways, going deeper and deeper into the archives, I've found you made > the same proposal almost exactly 10 years ago[1]! Oddly enough, it only > prompted one reply at the time - has the rest of the discussion been > removed from the archives because it was too rude? ;-) I think that you know that the answer to that is "no." And to be clear, the nasty comments that I recall weren't directed at me, and the rudeness was bidirectional (at least insofar as I remember the exchange accurately, which I may not). > Should we reopen > the debate now that some time has been spent without actions being taken > on that front? You *have* reopened the issue but haven't elicited a response. A nice characteristic of R is that if you don't like how something is implemented, you can offer your own version, which is what I did with contr.Treatment(), contr.Sum(), and contr.Helmert() in the car package, and similarly with Anova() in the car package. Sometimes these kinds of changes get into the standard R distribution, but more commonly, people who agree with you are free to use the alternatives that you provide.
