The why ?

Permit to easily detect what is supported in the current browser in term of DRM (Digital right managment) given a MediaKeySystemConfiguration.

for example:

[
  {
    "type": "com.widevine.alpha",
    "configuration": {
      "initDataTypes": [
        "cenc"
      ],
      "persistentState": "required",
      "audioCapabilities": [
        {
          "robustness": "HW_SECURE_ALL",
          "contentType": "audio/mp4;codecs=\"mp4a.40.2\""
        },
        {
          "robustness": "HW_SECURE_DECODE",
          "contentType": "audio/mp4;codecs=\"mp4a.40.2\""
        },
        {
          "robustness": "HW_SECURE_CRYPTO",
          "contentType": "audio/mp4;codecs=\"mp4a.40.2\""
        },
        {
          "robustness": "SW_SECURE_DECODE",
          "contentType": "audio/mp4;codecs=\"mp4a.40.2\""
        },
        {
          "robustness": "SW_SECURE_CRYPTO",
          "contentType": "audio/mp4;codecs=\"mp4a.40.2\""
        }
      ],
      "videoCapabilities": [
        {
          "robustness": "HW_SECURE_ALL",
          "contentType": "video/mp4;codecs=\"avc1.4d401e\""
        },
        {
          "robustness": "HW_SECURE_DECODE",
          "contentType": "video/mp4;codecs=\"avc1.4d401e\""
        },
        {
          "robustness": "HW_SECURE_CRYPTO",
          "contentType": "video/mp4;codecs=\"avc1.4d401e\""
        },
        {
          "robustness": "SW_SECURE_DECODE",
          "contentType": "video/mp4;codecs=\"avc1.4d401e\""
        },
        {
          "robustness": "SW_SECURE_CRYPTO",
          "contentType": "video/mp4;codecs=\"avc1.4d401e\""
        }
      ]
    }
  },
]

How it works ?

We are using a special API called mediaCapabilitiesProber provided by the rx-player, it's basically an abstraction of EME (Encrypted media extensions) API that work cross browsers.
