I distinctly remember arguing on this group a few years back with
someone saying that walk through tube trains would be impossible
because of [insert nonsense reason about loading gauge here]. Good
thing for them I can't remember who it was and I'm too lazy to go
through the archives otherwise there would be a serious session of I
Told You So right now.

I thought that TfL had considered walk-through for the 2009 stock on
the Victoria line, but rejected it as impractical.

AIUI, this proposed new stock is not intended to replace the 2009 stock.

I believe it was not TfL as such but Metronet (as was) who as the
agency charged with this upgrade decided it was too risky so they
took the safe approach to archive the target.

The fundamental failure of the PPP of course.
