Could it be to let them get experience with the effects of pathing the
ELL on to the NLL, before it opens?

That's what I thought, but it doesn't seem to work - it must either run
to Dalston Kingsland or Dalston Junction; if it's the former, then
wouldn't they need to build expensive and temporary turnback facilities?
If it's the latter, then there seems to be little point running a
precursor when the proper ELL could be run through.
