As noted on the ARG Github, you confused the Unbounded version of
Text_Buffers with an unbounded string (completely unrelated things), and
moreover, failed to notice that the language provides multiple ways to use a
Bounded Text_Buffer instead. So the language addresses this particular
concern.
I don't know if GNAT implements all of those ways (in particular, the
restriction Max_Image_Length), but that is hardly the fault of the language!
For anyone else interested in this particular discussion, I recommend
reading and following up on the ARG Githib issue rather than here
(https://github.com/Ada-Rapporteur-Group/User-Community-Input/issues/67).
Randy.
