Removing original external wall in roof

[HComplex]

My house had a two storey few years ago which involved installing a new section of trussed roof. It also required partially removing (the original) internal wall on the first floor to allow access to the extension, which meant the section above in the attic also had to be removed. This also had the benefit of allowing access to the new roof section from the original loft and hatch.

I'd now like to store a few light bits and pieces up there, but the removed section of wall inside the attic isn't big enough to easily get items through, therefore I'd like to remove some more of the wall. It's only a single skin of light aircrete blocks, and I know that the wall isn't attached to either the old or new trusses (the original 70's builders didn't use restraint straps but that's a separate issue).

I assume this is all fine to do, seeing as nothing is attached to or resting on that wall, however one of the longitudinal binders, and a diagonal wind brace is butted up tightly up against the wall. Could the wall be providing any support for those even though they aren't physically attached? As you can see from the photos, one of the longitudinal braces isn't using the wall anyway, and the end of it is floating in mid-air.

I'm a bit paranoid about doing something wrong as the new external wall is quite exposed and experiences quite high winds.

Thanks

I can't see that the (now internal) wall is doing anything above joist level, other than adding instability. I would be inclined to overlap the roof bracing from one side to the other, though.
