Of course.

However I think I have explained this. Here it is again:

1) The reason for the proposed change is that people should not loose
their changes to non-file buffer that they have said they might want
to save.

2) Currently if a user has set buffer-offer-save to t for this it is
lost if the buffer major mode for some reason is changed.

3) User data is lost.

4) There might be cases where some "smart" code actually delete the
buffer local value buffer-offer-save by intention implicitly by
switching major mode. Doing this implicitly hides the purpose and is
therefore easily broken and misunderstood since major modes is
normally not at all connected with whether the buffer content should
be saved or not. Rather these two things are more orthogonal.


Could you please explain to me your reason for asking the above
questions after all I have already written before about this? Have I
been to unclear so that you did not understand? Or do you think
something is missing?
