It could be of use to me, yes. I am recording it it!
It requires switching off algebra though, and frankly I really like the
work done by the Julia community for outputting their objects.
No plain text mail, sorry.

Personally, omitting the place of displayed type, time, memory usage and so
on, I prefer "data'' line cutted by the console. I am even asking myself
now if the underlying CL system does not have a way to interact with the
console for its parameters. More to look at. But, I "struggled" too much
with this, understanding the functions flows in outputting FriCAS objects,
I even loved the function 'name concatTrouble'. I'm not a big fan of coding
aesthetic things like this. Readability is also important of course and the
first time I tried Axiom, I was astonished by its 2D printing, do not take
my critics wrong.
I did not know your way of printing, I tried yesterday the formatted output
but had no output, I better understand now. The output is still buggy since
the output is no longer saved by the system command )spool, it's a pity.
There are rooms of work to do. One is using at Spad level I think #\newline
instead of letting the interpreter do all the job line by line (cutting it
etc.).
An example below with algebraic numbers à la Nemo (partially printed in
real/complex form). I really prefer your and my ways.
As one can see matrices are often very badly printed on screen, even if for
small sized matrices with small outputted elements that is a beautiful
work. Some options are available I think to better handle default mechanism
for matrices thought.

As you can see, I have the same output Ralf.
And sorry again for the non plain text mail.

P.S.: I use cut and paste console text in a themed editor before pasting
it here. This allows me to easily bypass the line cut done in Google Mail.
