These prices are insane. You can buy all (most?) of the lenses they’re recreating for a fraction of the price and adapt them to a mirrorless camera no problem. I bought a Helios 44-2 recently for $100 and adapted it to my camera for like $15.
To your point, none of those things are important if you're just a regular consumer and taking stills, but they're all really nice to have/important if you're working on a film.

For instance, Rokinon released a fantastic cinema lens line for consumer/prosumer cameras in the 2010’s, they were rehoused versions of their photo primes. They’re built entirely different.
The "Cinema" industry is notorious for gouging its customers, and this just yet another particularly egregious example of that gouging.
