I believe L2 flow control is pretty common.
Of course you're usually not going to see them even when using Wireshark etc., because they're handled at the MAC hardware level.
I'm not aware how to reliably determine whether link partner has L2 flow control / pause frames enabled. But at least you can check whether it's locally enabled:
Linux:
ethtool -a eth0
macOS:
ifconfig en0 | grep media
Windows Powershell:
Get-NetAdapterAdvancedProperty
Alternatively you can check Control Panel / Network Connections / right click adapter + select Properties / click Configure / Advanced tab / Flow Control value.
Note that above only applies to wired ethernet, not wlan.
