I would think no, the attribute list would be merged with the other
stuff when creating the layout.

"markup" is a shortcut for setting this attribute list.

Then to create the layout you copy the attr list, add "underline"
etc., then set it on the layout.

Maybe? I'm not sure.

"underline" is really a bit weird, the reason CellRendererText has it
is simply that you may want to tie it to a boolean column in the model
(i.e. there's value in just making this a boolean toggle for a cell
renderer). Maybe there's no real reason to do that for CanvasText.

Bug in something. ;-) It seems to render properly in the text widget
demo in gtk-demo; does that work on your machine?

That doesn't mean Pango always gets it right though. Actually the text
widget isn't using gdk_draw_layout(), so maybe gdk_draw_layout()
doesn't handle strikethrough. Try strikethrough in a GtkLabel and see
if that works.
