I think that's a move in the wrong direction and 'mutable' is indeed the way to go here.

(but not the same visual) So what about implementing it and let the rest have a look.

I believe so, too. That's why I am not going to throw anything in your head ;-} > PS2: another thing that I don't like is the fact that a bv is passed to > almost all methods in lyxtext.
