I tried adding different configChanges and sure enough, "navigation" worked! Now bluetooth controllers hot-plug nicely. So shall we add it as a default to the AndroidManifest.xml?
Funny that this is how this activity is described:
"navigation" The navigation type (trackball/dpad) has changed. (This should never normally happen.)
I think the reason behind this is because the bluetooth game controller I was testing doubles-up as a keyboard, which probably comes with a DPAD? It's a MOCUTE-032X_B63-88CE
Default launch mode (standard) allows multiple instances of the SDLActivity.

Not sure this is intended in SDL as this doesn't work. There are static
variables in Java, in C code which make this impossible (allow one android_window) and
also Audio print errors.
There is also some code added in onDestroy as if it would be able to
re-initialize: https://hg.libsdl.org/SDL/rev/27686adb08c3
Bug Android activity life-cycle seems to show there is not transition to get out
of onDestroy()

( can be tested with "adb shell am start my.package.org/.MainActivity"
and "adb shell am start -n my.package.org/.MainActivity" )
Send me a message if there are real use-case for this !
