Second that Adam.
Paul_Reed no offence, but local publishing is not very nice.
We might want to consider that WSUS is not only relevant for ConfigMgr. Which I personally believe is one or even the only reason WSUS is not sunset or declared deprecated with its general state in terms of UX and limitations and bare development investments since 2012.
Many SMB / SMC customers using WSUS and while Driver and FW via WSUS never gave any great experience for these customers in particular, local publishing would not be welcomed due lack of tools, outside the named for corps.
We have to consider that there is a 500+ seats limit to license corporate solutions via Enterprise Agreement like Microsoft Configuration Manager with System Center Updates Publisher. The majority number of companies do not have access to this.
