Withe the exception of NVDA, the other screen reader vendors are typically uninvolved in the standards process, so I would not expect feedback. As for NVDA, none of the other browsers expose even plain text generated content, so this likely just represents a problem that they don’t know they have yet. I did discuss this solution in the PF working group before proposing it to CSS.

That said, this change would not require the screen readers (including VoiceOver) to do anything special. It just changes the way the UAs expose a bit of text (or an image text alternative) to the accessibility APIs, so I don’t think buy-in from screen reader vendors is critical. This is a browser issue, and all the browser vendors have representatives in CSS.
