Yes, exactly. I think the fact the elizabeth line is not going to suddenly fix the station. It's a complete nightmare going between overground, jubilee, central, dlr and the exits.
I think that the elizabeth line may indeed cause station usage/interchange to grow as it will be very quick to get to places. EG: If you're coming hackney/dalston to go to heathrow you'd probably take the victoria and pic lines, instead you'll get people going east to go back via stratford as you can get the elizabeth line straight there.
This doesn't even account for the 10,000s of new houses being built and the masses of office space going up.
The report posted also shows:
"The Board discussed the update at paragraph 6.10 of the report, which related to the joint work being undertaken by TfL and LLDC in relation to improvements at Stratford station, in light of the very high usage of the station; the Board noted that the numbers using the station had doubled since 2012/13. It was agreed that a report regarding options under consideration would be submitted to the Board at its November meeting. This would include both short-term measures – including using the mobility access entrance on the Carpenters Estate, adding a temporary entrance on Montfitchet Road, and use of the mezzanine and eastern tunnel to ease movement through the station – as well as long-term measures and specific event day improvements. The Chief Executive noted that the short-term measures could have a significant impact and, in response to a query raised, that the majority of the obstacles to those, which had been previously discussed with the Planning Committee, had been worked through. The Chair requested that TfL representatives be invited to the November Board meeting to facilitate discussion of the options. "
Stratford will be one of the very rare stations which is both a very significant interchange and increasingly a 'destination' in its own right - which is challenging to work with. I think it will need a New Street/Reading-esque complete rebuild in the near future. Passenger numbers have doubled in 4 years, surely completely unheard of at a major station?
