These caps are a massive pain when downloading large games or OS upgrades for me as the end user. 500mbps is still fast but for a new protocol looking to replace older protocols, it's a big downside.

I don't really benefit much from http/3 or QUIC (I don't live in a remote area or host a cloud server) so I've already considered disabling either. A bandwidth cap this low makes a bigger impact than the tiny latency improvements.
