Generally, if you have to loop over all arrays to find common vertex
buffers, it's better not to do it. The default separate path is going to
perform best, because it's straightforward and interleaved arrays are
super rare.

I am currently away from all the source code and be back at about
the 22.4.
But out of my head: The main purpose of the is_interleaved_arrays
that I could
spot is to minimize the vbo's that are send down the pipeline. In
the non vbo
case the is_interleaved_arrays check did nothing I could finally spot?
The buffer itself is marked as user buffer and we need a new vbuffer
because
of the pointer value anyway? Correct?
So, the VAO now contains all the redundancy information. And thanks
to this
bitmask sieves we can easily collect the arrays belonging to a specific
precollapsed binding point.
So, the is_interleaved is fully there in the vbo case. Even better
as before.
It sees even 4 attributes distributed across two pairwise
interleaved vbo
arrays.
So even if you are fine, if you tell me that the user buffer code
can make use
of the same sharing finally, I can take a look at that and establish
the same
sort of sharing here.
best
