Should text style properties be disclosed to assistive technologies if platform accessibility APIs support it?

Consider a requirement that text style properties such as font, line spacing, indentation and justification be disclosed to assistive technologies if platform accessibility APIs support it.

The specific use case I have in mind is that a screen reader could use this information in determining how to present the text on a Braille device, for example by retaining aspects of the visual layout such as centred text or indentation. Boldface, italics and underlining may also be conveyed via suitable Braille indicators, but this is only possible if the underlying font information is available.

There may be other use cases, but this one is the best that ame to mind.

No file, test, or entry point is identified in the issue. First review the proposed text-style disclosure requirement against available platform accessibility APIs and assistive-technology use cases; done means reaching a documented decision on whether and how the requirement should be stated.
