what problems do arise due to this hack?

as you indicate below, this makes backports more complicated. I believe
the shlibs.local solution is more robust when having them in other
repositories like ubuntu, plf or debian-multimedia.

I don't see how this is less of a hack as a shlibs.local file. Can you
please elaborate?
