Currently, the value of the Build-Depends field is just copied to the final source package without making modifications. This is in contrast to the Depends fields of the binary packages in debian/control which can get mangled depending on their architecture annotations or substvars. What you propose would require mangling the Build-Depends field at build-time which is a bad idea for several reasons.
