I agree to defer everything you want to defer, but for things
to keep on level 3, I am a bit more strict, and there are a
few things you want to keep that I'd like to defer.

I am still not a big fan of this one. With the tweaks made to it recently,
at least I am not too worried about interoperability problems, but I am
still not a fan of the idea in general,

Is anybody other than EPUB pushing for this? If not, since we decided we
needed to talk more with them, can we ask them if this solves their use
cases? If it does, I am still not too enthusiastic, but if it doesn't
(and I think there is a chance it falls a bit short), I see no need to
have this at all.

Mostly ok, expect for the dependency on text-justify, which I want to
defer (see below).

I still have reservations about this. If we are going to keep it as is,
level 3 is where it belongs, but I don't think we should keep it as is.
I'll write a separate post about that.

I'd push this back. This is useful in a variety of settings, but it is
complicated, and I am not sure it solves the problems we want solved, nor
that it will lead to inter-operable implementations. I think this needs
significantly more discussion.

For values none, force-end, and allow-end, I agree to include in level 3.
But if I recall the use cases correctly, first and last were only useful
in combination with text-spacing, which you propose (and I agree) to
defer to level 4, so these 2 values should move to level 4 as well.

I'd defer these two. The single value variant, when used on non justified
text is not a big issue, but how this interacts with justification is
tricky, especially if you use the 3 value variant, or the advanced
justification rules proposed in text-justify (which I want to defer to
level 4).

Agree to defer all these

Defer sounds fine to me.
