My parents have it - first to do load balanced DSL, and then later to do DSL fail over for Starlink. Both of those features were critical during the virtual schooling timeframe and having enough bandwidth to support two school zoom sessions and household usage.

When discussing it with some of the sysadmins that I work with, they had a "hmm... interesting" thought with it - the configuration for it compared to the dual wan router setups that they have for their home labs is (from their standpoint) much easier.

The issue isn't so much a "can you do it" but rather a "how much time do you want to invest in designing your own setup?"
