I don't think I said that -- I can't speak for WebKit at all.  The
only things I know about it are what Maciej has said to me.

The thing is, I don't think there are any big problems.  AFAICT, the
use-cases are marginal and can be solved via JavaScript if people
actually want to.  So I don't see reason to maintain incompatibility
here.

Apparently search.blogs.ebay.com, or some page on it, formerly contained

if(vjo.dsf.client.Browser.bFirefox){oL.textContent=_d;}else{oL.innerText=_d;}

I don't know if this is very common, though, to be fair.

I don't know.  I haven't seen specific examples where innerText can't
behave exactly like textContent.  But Maciej said he's seen such
content, and newline handling is the only substantive difference in
Opera between innerText and textContent, so I assume it's there for a
reason.  It could be that such pages just break if innerText doesn't
exist.  I've certainly found such pages, e.g.,

http://beihai.gov.cn/5863/2010_4_28/5863_98289_1272423962000.html?open=1

A whole chunk of content is missing in Firefox.  Such pages seem to be
mostly East Asian.
