Your blazingly fast and thoughtful comment is much appreciated. Let's see what others have to say ... :-)
One clarification that I would like to make (which IMO diminishes your second point's potential value) is that the B2B SaaS platform that I plan to build would stay away from implementing a myriad of domain-specific scientific methods and algorithms (though I plan to provide a valuable core) and rather would enable users to integrate their own implementations (through a plug-in architecture). Thus, Julia's package ecosystem seems to be a factor of somewhat lesser importance.
