Why remove a feature other application might want to have or was the "moving a tab with MMB" specifically added for Konqueror's sake ? Anyhow, this patch does not really break "moving a tab with MMB" unless the user checks the "Middle-click on a tab to close it" option. Otherwise, the MMB click on a tab will continue to behave as it does now.

That results in the active tab being changed when a user activates the aforementioned option and clicks on a background tab with the MMB.

In addition to emitting a mouseMiddleClick signal which Konqueror currently relies on to close the tab, it also eats the MMB click event and generates a new LMB click event in its place. Apparently that was done for compatibility sake so that the user can move tabs using either the LMB or MMB.
