I would prefer upstreaming an option into home-manager, similar to #481

Agreed. Although, that is technically out of the scope of this PR.

What is the urgency of this change? Does Stylix fail to evaluate without this patch? Ideally, an option is upstreamed to Home Manager, so others also benefit from this.
