This has nothing to do with aesthetics and everything to do with reducing production costs. The sensors themselves add to costs, but then the data processing for all of this data adds to the computational needs of the system, sensor installs requiring calibration and flexibility for changes in sensors add costs. The list goes on.

Musk and Tesla are standing firm on their position that LiDAR is needless and that others will follow their lead here, but so far in practice the lack of LiDAR in Tesla vehicles has shown to be a serious disadvantage compared to other systems.
