Jet another reason is UI design and overall user experience: It's not obvious to many users what is going on when the visible length of the input field is reached as each character is shown as a star or big dot.

Technical solutions are possible but it is just easier to limit the length, e.g. to 20 characters, so that the cursor never reaches the end of the input field.
