Yes I agree, at the core my understanding has always been that webflow was built to be a designers tool by designers themselves, in the browser and with the convenience of world class hosting for those that could benefit from that convenience but again, at the core, it should still remain a tool (SaaS), but something that designers truly love because it makes our lives easier.
With the addition of the CMS capability it would make sense to leverage the built in hosting capability of webflow but to also remain a truly flexible designers tool, in which the CMS is also a part of, even down to export capability.
