A doable solution would be to group all the libraries related to a specific board together and release the corresponding JSON file.
For example, the libraries related to the Wio Terminal include
- Seeed_Arduino_rpcWiFi - master branch
- Seeed_Arduino_rpcUnified - master branch
- Seeed_Arduino_mbedtls - dev branch
- Seeed_Arduino_FS - master branch
- Seeed_Arduino_SFUD - master branch
- Seeed_Arduino_rpcBLE
- Seeed_Arduino_LCD
- Seeed_Arduino_Audio
- Seeed_Arduino_LIS3DHTR
- Seeed_Arduino_RTC
- USB Host Library SAMD
- Adafruit TinyUSB Library for Arduino
- SparkFun_BQ27441_Arduino_Library
See the GitHub ticket at Include all the Wio Terminal related libraries into the Seeed URL json.
