I tested an upgrade from Bionic to Focal with -proposed enabled (I had to remove the disabling of -proposed in DistUpgradeController.py) and did not encounter any of the following error messages:
GLib-GObject-WARNING **: specified class size for type 'PangoCairoFcFont' is smaller than the parent type's 'PangoFcFont' class size at /usr/lib/x86_64-linux-gnu/perl5/5.30/Glib/Object/Introspection.pm line 67.

I had seen them when I tried upgrading the same virtual machine when -proposed was not enabled.
