Seriously. As Quim and others have been telling us over and over, don't worry about it. It probably shouldn't be in your review, because your discussion of the topic makes readers worry about something that they shouldn't be worried about. If you look at the wiki, mailing lists, talk threads etc, you'll see that the /opt thing is very new, and it will take some time to get that all sorted out. I know that most community developers are planning to put their stuff there, and I'm sure all of the apps in the repositories will get the maemo-optify treatment, too.
