Well, that's all a matter of opinion. I'll admit I can see how these might
be useful, but lets focus on whether or not these are bugs. To find this
out, I decided to do a little research to see if I could find where this
functionality was documented so we could find exactly what a Window Manager
is supposed to do with regard to Xinerama. This search came up woefully
short of anything resembling an authoratative source. The closest thing was
a Xinerama HOWTO. So, I turned the XFree86 Xpert mailing list for some
guidance regarding Xinerama documentation. Below you will find my post and
the response.

There aren't any. The protocol that was featured in the original
Xinerama implementation was not useful and it didn't give window
managers the information needed. I added new protocol, but it's
not official and is expected to be replaced by an official version
from X.Org eventually.
Basically window managers don't *have* to do anything. If
you want to do things like resistence when moving windows between
physical screens or placing popups someplace other than right in the
middle of two screens there's enough information in the current
API to do that. The API, defined in Xinerama.h, has functions for
querying if Xinerama is enabled or not, and allows you to retrieve
the actual number of screens and their locations on the single
logical desktop.

As you can see the author clearly indicates that there is no offical
guideline for Window Managers at this time. Additionally, he clearly states
that "window managers don't *have* to do anything". This would indicate
that the manner in which BB handles the maximization, dialog display, window
placement, and any other thing you can think of with regard to Xinerama is
not a bug.
IMHO, this was clear from the basic discription of what Xinerama did. That
being making multiple physical monitors appear to X as one logical display.
Thus if I want to maximize something, I want to maximize it. The creation
of virtual resistance boundaries or window placement guidelines is a purely
voluntary item.
