The original IRT and BMT stations in Manhattan got it right; s short distance down directly to platform level. Quick

There were less underground utilities to contend with back then.

Now, there are other subway lines, water, sewer, telephone, Cable TV, and steam and river and creek beds.
Ideally the deep bore routes should rise up for stations as the IRT ROWs did to aid in stopping and starting by using gravity.
