I confess, I had in mind also potential improvements to EmuTOS. :-)

Ok.

Before it's going to be default, it needs to be tested
(couple of weeks of use with Atari binaries linked with
different libs & linkers should be enough).

Such a script will help you and other debugger users in
doing that.

However, I think something like that could be also of more
general use.  So, please consider what such a script
could & should do.

By extending the same reasoning, why Hatari shouldn't
invoke debugger on every exception?

(Debugging use-cases are different from non-debugging
use-cases and debugging settings can have downsides for
normal emulator usage.  While not as drastic, automatic
symbol loading for terminating programs can also have
downsides, at least it generates extra output to console.)

I wonder how they happened to run Hatari in the first place.
By accidentally installing and running Hatari, when their
cat ran over the keyboard, perhaps? :-)
