It's a way too important a paradigm not to use it.

I didn't say it's a catastrophe, I said it gets in the way.  IOW, it's
a nuisance (IME).

No, that doesn't delete the region.  Perhaps you meant C-w.  And in
any case, the fact that I typed C-w already says that I didn't just
want to return to the marked place.  So I don't think this analogy is
valid.

Like I said: it gets in the way.  You disagree, which is fine, so you
can enable delete-selection-mode in your configuration.  I tried that
once, and quickly disabled it back, due to the above (and similar
issues).
