I don't think so. Are FOP developers aware of the fact that DocBook
stylesheets insert soft-hyphen (U+00AD) character at all places of
possible break? This characters marks possible places for hyphenation.

Of course U+00AD is defined in Unicode and not in XSL-FO.

It would be nice to ask FOP developers why they think it is abuse. I
don't see any evidence for this neither in Unicode nor in XSL-FO spec. I
think that this probably lives in area where exact behaviour is
implementation dependent. So obvious thing to do is to follow useful
behavior of market leaders (XEP, XSL Formatter).
