@angular/cli: 1.6.0-rc.0
@angular/platform-server: error
@angular-devkit/build-optimizer: 0.0.33
@angular-devkit/core: 0.0.21
@angular-devkit/schematics: 0.0.37

Desired functionality

An up-to-date Angular 5 will not have @angular/http as a dependency as it is now deprecated in favor of @angular/common/http, and @angular/platform-server requires it.
(as discussed in #276 it should even be removed from the default schematics)

The universal schematics should do the extra mile and check if the dependency is in the package.json and add it if necessary, as it does for @angular/platform-server.

This can be closed now that #12392 from @lacolaco has been merged.

(I am the original poster of this issue on devkit, but I can't close it myself now that the issue has been moved to angular-cli, @alexeagle is now the owner).
