Currently, no, the tabs implementation doesn't check for this.  I'll look
into it.

That is not consistent with how things work in Aquamacs.  I appreciate that

Apart from philosophy: tabs are designed to be window-dependent -- you can
display the same buffer with a tab in two different windows, and close that
tab in one window without affecting the other.  Tab display has to change in
this case without affecting the buffer list.  Similarly, some buffers should
not be killed when all their tabs are closed (e.g. *Messages*), so we can't
look to a buffer list to determine which tabs should appear.

Given your particular usage and desires, you may want to try tabbar.el
without the Aquamacs enhancements to tabs.  Alone, it doesn't follow the
modern conventions for a tabbed interface, but it might suit your needs
better.
