Roboute Guilliman's tacit tolerance of chapters growing beyond the thousand-Marine limit is interpreted as a pragmatic response to military need. This is a distinction between tolerating expansion and formally changing the rule. Removing a limit would still leave formations needing time to build their strength. Replenishing existing chapters to their authorized numbers provides immediate readiness, while allowing further growth prepares capacity for later crusades. Formations away from active fronts may have more opportunity to accumulate personnel. The strategic argument is that Guilliman must eventually regain the offensive against Abaddon, whose preparations have already achieved their primary objectives. In this fictional war, changing force policy and generating the troops needed to act on it are separate tasks.

Building force strength for a return to the offensive
Guilliman's tolerance of oversized Space Marine chapters reflects a force-generation problem: formations must grow before a state can sustain offensive action.
