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.
The article says they’re adapting to mirrorless cameras
> As reported by CineD, the new Air series of lenses is designed to cater to the growing number of filmmakers who are using compact, lightweight mirrorless bodies for high-end professional work.
> The IronGlass Air lenses move away from IronGlass’ standard PL-mount cinema design toward compact, mirrorless-friendly designs
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.
Being it either a low quality lenses in which people see a artistic quality of manufacturing defects or text from Dostoevsky which ruminates in extended length the inner thought process of a moronic character which some mistake for a mysterious russian soul.
I own Helios lenses with Zenit camera I inherited from my father which is of the sentimental value as it was a first significant purchase after my parents wedding, and most of my childhood photos are done with it, but even my dad will trade it for a good Nikon lenses without a second thought.
I googled it and all the pages were just this company saying "Yeah! We rehouse amazing soviet era lenses in modern lens bodies!" | Which is cool, but where's the "legendary" part of the story? Like, why would you want one as opposed to another lens?
Stuff like that happened repeatedly: GAZ Chaika was a copy of Packard; SM-1 computer was a copy of PDP 11/34; Tu-144 looked just like Concorde, etc. etc.
Tu-144 was not a copy of the Concorde. (Convergent evolution is not the same as copying a design!)
The Soviets did clone a lot of DEC gear but I don't think SM-1, specifically, was a DEC clone. (In this lastmost case, the Soviets were left cloning computer equipment because it was forbidden to export to COMECON states)
Another example I forgot: the first Soviet nuke was directly copied from the stolen Fat Man design. Of course later they did novel stuff, especially the fusion designs of Sacharov et al.
It is well known that KGB got hold of the Concorde blueprints, so yeah, not a direct copy but certainly a lot of influence in that design. Again. the details like engine performance made the difference: apparently Tu144 had to continuously use afterburners to stay supersonic. It was also quite unreliable---I've heard that towards its end of life it was just flying cargo and airmail.
Due to this, these lenses developed a cult following, and even more now that some prominent cinematographers used in some high caliber productions (The Batman (2022), Dune (2021)).
