Concerning section 5d of the final text of the GPL 3:

Could this requirement be interpreted more liberally? I'm concentrating
on the bit from "however". Suppose: I receive a program under the GPL 3.
I create a new interface for the program, without the legal notices.

The license says that, when distributing my modified version, I "need
not make" interfaces of "the Program" that don't display a legal notice
display a legal notice. I think, then, to be exempt from the requirement
to make user interfaces display legal notices, my modified version of
the Program would have to count as just "the Program".

Consider that "The Program" is defined as:
>  "The Program" refers to any copyrightable work licensed under this
> License. 
When I convey a modified source version, 5c) requires the entire
modified work be licensed under the GPL. This then means that when you
convey a modified "the Program", the new bits are licensed, and so the
whole modified program becomes just "the Program". I do not need to add
legal notices to interfaces of "the Program" that lack then.

I'm curious how far fetched people think this is.

If this interpretation were true, then the only burden of this section
would be to keep the legal notices in the user interfaces that you keep,
but you would *not* be required to add any notices to any user
interface, regardless of whether you wrote the interface or not.
