How about calling this property allow-widow-recto-last-page? Maybe it's a bit of a mouthful, but it describes what it does on the can: the higher you set the value the less likely it is that ly:page-turn-breaking will produce a last page that is recto page if you're interested in doing duplex printing when you produce the PDF. "Widow" is used for lonely single lines in typography when the rest of the paragraph is set after a page break. Recto (normally) means odd-numbered (if you're starting page numbering at 1) because it's the right-hand page of a double-page spread, verso is the left-hand page of the spread, and is generally even-numbered. Just a thought I had in the bath after reading this thread.
