What’s the purpose of ScriptSig in a SegWit transaction?

Here’s an example of a SegWit transaction that also contains data in the ScriptSig field:

{   "txid": "954f43dbb30ad8024981c07d1f5eb6c9fd461e2cf1760dd1283f052af746fc88",   "hash": "a5947589e2762107ff650958ba0e3a3cf341f53281d15593530bf9762c4edab1",   "size": 231,   "vsize": 148,   "version": 1,   "locktime": 0,   "vin": [     {       "txid": "56f87210814c8baef7068454e517a70da2f2103fc3ac7f687e32a228dc80e115",       "vout": 4,       "scriptSig": {         "asm": "002001d5d92effa6ffba3efa379f9830d0f75618b13393827152d26e4309000e88b1",         "hex": "22002001d5d92effa6ffba3efa379f9830d0f75618b13393827152d26e4309000e88b1"       },       "txinwitness": [         "3044022038421164c6468c63dc7bf724aa9d48d8e5abe3935564d38182addf733ad4cd81022076362326b22dd7bfaf211d5b17220723659e4fe3359740ced5762d0e497b7dcc01",          "21038262a6c6cec93c2d3ecd6c6072efea86d02ff8e3328bbd0242b20af3425990acac"       ],       "sequence": 4294967295     }   ], 

If the txinwitness is the new location for the “unlocking script” section for a vin (as opposed to the old scriptSig field), then why would this transaction still have data in its scriptSig field?
