Comment (by afercia):

 Looking back at this issue, the main problem with clearing the ARIA live
 regions after a certain delay is that the delay value would be totally
 arbitrary. For example, let's consider a 10 seconds delay. What happens
 if, after some user action, a ''second'' message is sent to the ARIA live
 after 10 seconds or a bit before / after? Would screen readers be able to
 get the text change soon before or after the regions has been cleared? In
 my experience, screen readers need some time to get aware of and announce
 a text change. Thus there's always the change they might miss a text
 change and not announce anything.

 During the recent WordCamp Verona (Italy), [https://github.com/MignamiS
 Simone Mignami] suggested an alternative, simpler, option. Placing some
 visually hidden text before the ARIA live regions would allow to
 communicate those are a "notification area", letting users understand the
 text is a notification that might be no longer relevant. I'd like to hear
 the accessibility team thoughts on this approach, which seems reasonable
 to me.
