I don't know all that much about the conventions for this under Linux,
but I'm familiar with other Unix-oid platforms where shared libraries
*must* have execute permission or they flat out don't work. (HPUX is
that way for sure, and I think most BSDen as well.) So it would not be
surprising for upstreams to prefer to install 0755 everywhere for
portability. I think Debian is on the wrong side here, if your
informant is correct about their policy in the first place ...
