How is there an issue when any given module could be built-in instead?

The general trend is to make all PCI host drivers modules, the primary
reason this one, IIRC, is not a module is because it is missing
remove() hook to de-init the PCI bus. Not too hard to add, but I
wanted to do a common devm hook to do that instead of an explicit
.remove() hook in each driver. I suppose we could just ignore that and
allow building as a module. Unloading is optional anyways.

That's a comment for the series more than just this patch.
