I said it *can* cause a bad performance.  I didn't say it always causes
a bad performance, just to be clear.

IOW, all I said was people *can* experience a bad performance with large
enough documents.  They may, or may not, depending on their
circumstances.

And I hope I've already explained to you that Excel can't, or at least
Excel can't guarantee that bad performance won't result under any
circumstances.

I disagree with your last line, or maybe you and I have a different
definition of dialog modality (which is possible, since you see it from
a designer's prospective while I see it from a developer's).

The reason why I call the dialog modal is simply for the following two
reasons:

1) You can't edit cell contents while the name manager dialog (the main
dialog with the list box) is up.  You can't even click on any cells to
set cursor there.  While the dialog is up you lose the editing
capability.  All you can do is change the names within the dialog.

2) Excel performs re-calculation *only when* you click 'Close' to
dismiss the main dialog, the dialog whose screenshot you referenced
above.

Anyway, I simply want to invite you to just play with Excel 2007 or 2010
at work and draw your own conclusion.

Best,

Kohei
