I was finally able to get the browser approach to work (advice: there is a little slider at the very top of the gnome-extensions-app GUI that you have to click to get the extensions to activate, or else you begin to lose your mind thinking that you have to install it manually from source because clicking on the slider next to Appindicator and KStatusNotifierItem wasn't doing anything when I clicked it).
I find that the CPU usage has improved. When I am running indicator-multiload in the top right corner (i.e. in the gnome status bar) I find that gnome-terminal takes up 7% of one of my cpu cores (and this drops to less than a percent when I turn off indicator-multiload). Earlier on 2022-03-01 I wrote that gnome-terminal was taking up 30% when I was running indicator-multiload (and of course it dropped to zero when I killed indicator-multiload)
So fixed version 53 is definitely an improvement (thanks!). I am not sure if the bug can be declared to be squashed but this is much better than it was.
Again I am using Ubuntu 20.04 which uses Gnome 3.36.8 by default.
