The console has many instances of old variables, $grid-float-breakpoint and $grid-gutter-width, controlling margins/padding and responsive breakpoints throughout the Admin and Dev Console. These do not provide spacing and behaviors consistent with Patternfly components which use their own variables, $pf-global-gutter-md, $pf-global-gutter, and $pf-global-breakpoint-{size}. By replacing these, the intent it to bring the console closer to a pure Patternfly structure and behavior, requiring less overrides and customizations.
