And we would also arrive in questions like: If equation brings its own algebra

It's not an "algebra system": it's just a few convenience operations.
It should not be confused with allowing Equation to be used in places
where Expr is expected.
Might it be an idea to introduce functions such as AddSides,
SubtractSides, etc that Mathematica has? Not only would these avoid any
confusion with the normal arithmetic operations, but I think using
these functions would clarify what is going on. After all, when people
do such operations by hand, they don't write (a=b)*k,or whatever, they
typically write "Multiplying equation 4 by k we get..."
