I agree we need a good reason for not just using deferred probing, and PCI host bridges in general are no longer something that needs to be probed early. If you have a particular use case in mind that can't be solved in a better way, we can talk about making this an earlier initcall (probably not arch_initcall), but in general we try hard to avoid new ones like this.
