I'm not sure that's the case, Tesla has cut all sorts of features over this time to continue delivering vehicles from lumbar support to radar sensors to steering components necessary for the redundancy required to bring FSD to anything beyond a Level 2 ADAS.
Almost all of Tesla's sales are the Model 3 and Y, which share like 75% of their parts if I recall correctly, and with limited customization options. Just the simplicity of the supply chain is likely a big factor and is likely a big factor in Tesla's current profit margins.
