I think in practice it will work well, given that bufferbloat is often the cause of congestion on a home network. TCP itself is usually quadratically impaired when it comes to reacting and backing off in the face of increasing latency caused by buffers (uploading a large file through Dropbox or Google Drive will most likely cause ping times on other machines on the same network to degrade from milliseconds to seconds). When it comes to bufferbloat, a single TCP flow can dominate all others and be highly unfair because TCP's congestion algorithms are so slow to react (they often only react to packet loss and not latency). LEDBAT and delay-based congestion algorithms were designed to handle bufferbloat well, and PCC is essentially a superset of these, taking into account loss rate and throughput in addition to just delay.
