No, but I don't see that we need to. This only seems to be active on
servers under the name aspmx.l.google.com; in the same session Exim
falls back to the other MX records for the domain(s) in question and
send the remaining messages down that connection instead.
Although this is not strictly RFC compliant behaviour I have not seen it
actually cause any problems whatsoever - perhaps a one or two second
delay in delivery to Google, that's all.
I think I'll ask our work Google Apps contacts about it, see what they
say.
