You missed the possibility of keeping bracketed paste mode (the
functionality) enabled (as I, for one, have had it enabled ever since
bash added this feature, which was like version 4.3 or 4.4 or so), but
configuring (patching?) bash not to use inverse colors for pasted text.
Use regular colors as it used to do, or some actual coloring (e.g.
magenta), or underlining etc.

If it's good enough for text highlighting in all GTK apps, including the
Firefox browser, then I doubt there would suddenly be a11y
considerations arising in the terminal. But of course I might be missing
something.

I can't think of any other easy way. I mean, for example Terminology
uses fancy diagonal shading and stronger contour for the highlighted
area, but I highly doubt gnome-terminal (vte) would do anything similar
any time soon; especially if GTK doesn't have such a feature either.

Also don't forget that presumably about a dozen other terminal emulators
suffer from the same problem. If you choose to adjust terminals to bash,
rather than the other way around, you'll have to do it with many-many
terminals. I don't believe it's the preferred approach.
