There are two very different issues; structure and presentation. It is
cumbersome to always write proofs out in full, so working
mathematicians use a set of informal shorthand notations.

I believe that such courses fo into more than just the logical
machinery needed in Mathematics, and that they cover, e.g.,
independence, consistency, models.

There is no syntactic identity there. There is, instead, an identity
based on a specific[1] definition of the notation and a specific set
of axioms.

[1] Well, some of the posters seem to be unable to formulate what
they mean by, e.g., "0.999...".
