I agree with you that `bounds-of-thing-at-point' needs some work.  I have
noticed other issues with it.  We might work on them once we fix this bug.

In the example in this thread the problem arise because
`thing-at-point-bounds-of-list-at-point', which is the actual
function doing the job here.  We need to fix this function.
Without it, the previous example works:

emacs -Q thingatpt.el -eval "(require 'thingatpt)"
M-: (put 'list 'bounds-of-thing-at-point nil) RET
> C-p
M-: (thing-at-point 'list t) RET
=> nil
