That's a MOO - some would be highly embarrased to lose to a team generally seen as massively inferior (see England vs Aus "A" 1998\99 for instance - created a huge amount of tension as England were seen to have gifted victory on a plate for the sake of match-practice).
The result isn't, obviously, as important as those of the Tests\ODIs, but equally - as I've said about 100,000,000,000,000,000,000 times, individual performance = team peformance, and as such if you lose it means many of your players are likely to have performed poorly and this does matter.
