Resizing code partition

[quenthal]

With some components (especially BT proxy and ble_tracker) there is note:

"The first time this component is enabled for an ESP32, the code partition needs to be resized. Please flash the ESP32 via USB when adding this to your configuration. After that, you can use OTA updates again."

If I add just one of those components (and flash with USB)... and later want to add additional component that also requires resizing of code partition, do I need to again flash using USB? Or is this resize requirement one time requirement?

If I remove the only component (that required resizing and USB flashing) can I remove it by flashing OTA? If yes, and if I re-add it at later point of time, is the resizing still in effect or does it need to be reflashed using USB?
