Yes, we need it and, if I'm reading correctly, Laurent doesn't say the
oposite.

BTW, Debian also has a versioned development package and the neutral
symbolic link. The symbolic link ensures the neutrality with regard to
the version. Thus:

-rw-r--r--  1 root root   251 Nov 27 20:56 libpng12.pc
lrwxrwxrwx  1 root root    11 Nov 27 20:56 libpng.pc -> libpng12.pc
