"...hurdle for broader industry adoption..." and "...could be motivated by the company's focus on scalability and market penetration..." tell me that there is clearly a market segment requiring the higher-end processors of the Pro models but which don't necessitate or "just don't want" the higher-end HDR displays. Providing a lower unit-cost non-HDR Pro that satifies both needs along side the existing HDR XDR models seems like a marketing no-brainer, Apple would be wise to grab that "cash sitting on the table" and expand its user base.
