(MDI is "Multi-" and SDI "Single-" Document Interface, AFAIR. In an MDI
applicaton, an application main window contains a child window for each
document opened in the application. With SDI, an independent window
opens for each document, and there is no main application window.
Something like that. And I haven't seen an MDI application for some time
now, I think.)

Would these be "normal" Emacs frames like one gets with C-x 5 2? Or are
these frames special in some sense, like a Corfu child frame displaying
completions (possibly with second child frame displaying additional info
for completion candidates), or a Posframe chlid frame displaying a
Transient menu, or somehting like that?
