Well, there remains the fact that we've seen no field reports that seem
to trace to failure-to-acquire-AEL since 9.6 came out. So arguing that
this *could* be a probable scenario fails to comport with the available
evidence.
My inclination is to fix it as I've suggested and wait to see if there
are field complaints before expending a whole lot of effort to create
a better solution. In any case, I am not willing to create that better
solution myself, and neither is Robert; are you?
