I agree. Put even more pointedly, Andrew's proposal is
exactly opposit to the one I have been making since several
months: For me the integration of the s3 and s4 components
is the only major thing that needs finishing for 4.0.
Everything else is also doable for 4.1 or later.
(I might be neglecting todos from the AD world that I am
not aware of.)

Put differently, Samba 4.0 will correctly be expected to be
a superset and replacement of Samba 3.X.
If we tell the people, hey this is 4.0, you have the new
AD controller called "samba", but you can also enable
those legacy features with those legacy commands (smbd, ...),
then this is at the very least misleading and confusing.
I am all for releasing a 4.0 soon, as I have mentionend more
than once in the past (since more than a year now) but IMHO,
we should fix the integration of the components before the
4.0 release. The discussions of how to do this has been going on
since several years now and has been deferred again and again.

To my understanding, this is what release branches are for. :-)

This would basically mean that 4.0 will be a AD-only release.
The s3-fileserver components would just be dropped as a
snapshot and whoever wants to seriously use those components
should use the 3.6 release or wait for 4.X? I think this is
counterproductive and setting the wrong signs for our users.
For me Samba 4.0 should be not be the result of the
samba4/source4 development efforts but the superset of
s3 and s4 development, the outcome of our combined efforts.
I repeat, for me the only decisive and strictly necessary step
for releasing 4.0 at this stage is that the intergration efforts
are completed. All fileserver or AD featurs that are missing or
incomplete can be added later on.
