This matter was raised in March:
https://stat.ethz.ch/pipermail/r-devel/2019-March/077457.html

In principle, I agree.
However, I'm not sure it's possible without causing compatibility problems.
Not to mention all the disagreement about what's the correct approach.

And I should probably apologize for incorrectly suggesting that there
was a non-backward-compatible design flaw...
