Session-based WAN balance (like Draytek and others)

[sersis]

Draytek (and so other vendors) has a new solution called Session-based WAN balance that seems to bond multiple WAN to have a mora stable and powerfull connection to Internet. (see here for more info: https://www.draytek.com/en/faq/faq-connectivity/connectivity.lbpr/what-is-the-difference-between-ip-based-and-session-based-load-balance/ )

It is possible to see something like that in te OPNsense future?
