"" does not ever mean "Main Page".
When a visitor reaches the web site, but no title is specified, we have
nothing to display -- so we send them to the locally defined main entry
page.
This is a user interface activity.
There is no time or place that we would or should ever interpret "empty
title" to mean "Main Page" in any other kind of interaction or i/o. To
do so would be egregiously wrong and would be very likely to cause
strange, mysterious, hard to track down breakage.
