With only libpng-dev as you say, the build daemons would not know which
of the two versions to pick when both would be available, no?

I recall that even lintian warns about this
(virtual-package-depends-without-real-package-depends) and suggests to
never depend on a virtual package without a real package as an
alternative first.

At minimum, we'd have to depend on libpng16-dev | libpng-dev, AIUI,
right?
