Well, since I fear Roberto is not active, I think no.
When I see no further reactions I intend to handle it as usual and apply
patches without sending them to the mailing list first, though this is
a change I want to make sure nobody has objections anyway, e.g. because
they are attached to having a bit-exact color space conversion since the
codec is called "lossless ...".
Once I've read more of the code I don't mind adding myself as maintainer
so people know who is familiar with the code.
