For those that don't know the details of the technology, both the space vehicle and ground terminal must know and accurately report their information in order for both sides to properly compensate for the Doppler effect.

This isn't fully true, the terminal needs to know the satellite's position and velocity but the satellite does not need to know the terminal's location. All the Doppler and time delay compensation happens on the ground side. The terminals transmitter compensates for Doppler and time delay so the signal at the satellite is at the correct frequency, otherwise different terminals would interfere with each other as they will not be frequency and time aligned at the satellite.
From the down link prospective the satellite broadcast to a spot/cell which corresponds to a location on Earth. The satellite does not compensation as even terminals within the same cell will require slightly different frequency shifts and time delay shifts, which the user terminal compensates for.
Now I don't work for Starlink but do work for one of their largest competitors and having the user terminal do all the compensation is by far the easiest method. Our terminals report to a server their GPS XYZ position so we still know where they are located, but for receiving a signal from them the terminals only need the satellite's positional information and the satellite only needs to know the spot ID.
