Sorry, no, it’s not a perfect solution, just a workaround. Best practice would be to use what is explained here.

As said previously you cannot change the Name field, and to exclude or modify his description you can’t even (so far i know) modify the default view level (All) for that field.

So you have to use another CSS trick and perhaps add an “only me” message to the Name field description.

#field-visibility-settings-toggle-1 {
display:none!important;
}
