No, that is useless. - It does not change a thing.
The buildds do not automatically evaluate Build-Depends before they
download and try to build the package. They download the package,
install build-dependcies (ignoring the version requirements) and only
after that check whether the version requirements are fullfilled.
Let me show you the different outcomes on a autobuilder with old
kdelibs:
* with versioned Build-Depends:
buildd downloads package and tries to install kdelibs4. apt screams
loudly because libopenexr0 is not available.
* without versioned Build-Depends:
buildd downloads package and tries to install kdelibs4. apt screams
loudly because libopenexr0 is not available.
The buildd administrators can *manually* set pre-dependencies to save
buildd time (Dep-Wait),buttheycan do that no matter how the
Build-Dependencies look like.
