I welcome many of the new features. It's great for designers who are more technically oriented, though enterable input fields would be nice.
I do wonder how non-technical designers are going to feel. The learning curve is definitely going higher.
I'm worried about the rather pricey per / seat cost. There are far more developers than engineers at most organizations, and this is really going to hurt the licensing cost. Definitely Adobe bean counters flexing its muscle.
Design systems, tokens, modules, over the top consistency/reuse, the programmatic approach to design is experienced by some as a major buzzkill.
It's now way easier to both stop designers from adding one-off design and interaction patterns that confuse users and to write truly reusable components that allow us to iterate faster as a company while maintaining a high level of visual consistency and polish. That's a big challenge once you start hitting org sizes in the hundreds or thousands.
But I still empathize with those designers. It's mechanized design which to some feel like a prison for their creativity. Even more so when all designs start to look the same across companies, and then there's AI design still to come.
What you emphasize, speed/productivity, is indeed the credo of our world, but that doesn't necessarily align with the goal of design. Take Apple, they don't seem to care about speed or continuous delivery at all, yet are widely celebrated for design excellence.
Likewise, "consistency" does not mean you found the optimal design. Even Google admitted that Material Design was a poor choice for some of their (internal) products and couldn't make it fit.
