I don't think I want any crawler ever hitting my API endpoints for customer lookups, scheduling, inventory management, etc - all that stuff that is the 'Application' part of 'SPA'.

Why people use js/spa/etc stuff as the basis for a content/marketing site... I don't know. I mean... yeah, I know why - mostly to expand their skill set. But there's usually no functional benefit, and usually some drawbacks, as you're pointing out.
