Back in the
early days of the odious origins of the jargon word
"notability", back when it was a buzzword on VFD meaning "I haven't
heard of it," people would raise this as one of the spurious arguments
that made no sense on a moment's reflection. Like the one that too
much text would overload the servers, so the okemon articls had to go.
Please don't say this stuff without at least a moment's thought on
whether it actually makes any sense.
I do try. Hint: this was about summary style spin-off articles, and
where the line is drawn there. Not about notability in general.
Replace references to notability above with WP:SUMMARY, and it might
calm you down.
I was going to disagree with your comment, too, though not quite on the
same grounds as David Gerard. There can "aesthetic" grounds for
objecting to global imbalances of coverage; but they really have no
status. Disproportionate coverage can be a problem under NPOV. Otherwise
I think it shades off into being a writing issue: where we favour
concision as better for the reader.
