Your experiment uses the 'exit' command to test whether aliases are supported.
However, 'exit' is a shell built-in. Whereas 'sed' is not and will likely
never be a shell built-in. Can you retry your experiment with a non-built-in?
In gnulib-tool line 468 you see that the usual way to override built-ins in
bash is to define them as a function, because 'alias' does not work for them.
