Clearing known networks through control request doesn't issue a system event

When I call CTRL_REQUEST_WIFI_CLEAR_KNOWN_NETWORKS through a BLE control request it doesn't issue a network_credentials_cleared event from my network manager event handler. It does when I call WiFi.clearCredentials() though.

When called with WiFi.clearCredentials(),

[ncp.mgr] TRACE: Updated file: /sys/wifi_config.bin
[system.nm] TRACE: Updated file: /sys/network.dat
[app] INFO: Network credentials event: network_credentials_cleared

When called with a control request,

[ncp.mgr] TRACE: Updated file: /sys/wifi_config.bin

It looks like this is because the control request calls,

ctrl::wifi::clearKnownNetworks(req)
└>wifiMgr->clearNetworkConfig()
  └>saveConfig(networks)

while WiFi.clearCredentials() calls,

NetworkManager::clearConfiguration()
├>wifiMan->clearNetworkConfig()
| └>saveConfig(networks)
└>NetworkManager::saveStoredConfiguration()
└>system_notify_event(network_credentials, network_credentials_cleared)

Is this intentional? I had been trying to keep track of wifi networks being added and cleared through the event handler because I didn't know if calling WiFi.hasCredentials() all the time was a good idea.
