Maxlength hard limit doesn't work for CKEditor 5 widget

I understand that you would expect from the config to act as a definitive limit when turned on and truncate the string once it is switched on.
However, it implies that the field can hold more characters just well, before the option was not turned on, so having the string truncated on form load, would render part of your pages unreadable due to the loss of strings after the save operation. I find that a bit harsh and disturbing from the editor point of view.
