The Queen's Park - Stratford service ia a post-2012 development that

It doesn't - TfL's phasing ties the two together, but Network Rail
recommend the Queen's Park service go ahead in isolation from the
Bakerloo Line changes.

Although ISTR (from the Cross-London RUS?) that in that case the
trains couldn't reliably be reversed at Queen's Park amongst the
northbound Euston DC services (which would use the same platform), so
they'd have to run through to Willesden Junction and reverse in the
bay platform there instead. This would have a consequent negative
impact on Bakerloo performance.
