Yes; whenever this topic comes up, I comment that the problems are
with the approaches and not the capacity at termini, therefore not
addressed by freeing up more platforms at Waterloo.

The South Eastern side of Victoria is very underused, and Waterloo,
with its long turnaround times compared with somewhere like Charing
Cross, isn't exactly stretched.

The problems are Borough Market, the two two-track routes between
Bromley and Victoria and the two-track route through Queenstown Road
on the "Windsor" side.

But that doesn't explain why they're not planning to send some
suburban Charing Cross trains to Waterloo via Lewisham and Peckham
Rye. That would help to free up the Borough Market tracks without
adding to congestion between Bromley and Victoria.
