I tried, but svg is not great, it has many unfixed problems with scaling
and backgrounds. OTOH, I hope with canvas it would be easy to draw such
shapes around the tab name like in web browsers shown below, and also
to implement overlapping tabs. At least canvas in web browsers allow
doing such custom drawings.
As for the implementation, there is already Cairo code used to draw 3D box
shapes around strings with box faces in xterm.c. Canvas could be
implemented to generalize these hard-coded shapes and expose their
definitions to Lisp as configurable options.
