I stand corrected.  They are experimental. Nonetheless, they are not proprietary specs for the cable industry. 

The DOCSIS implementations of L4S are entirely in firmware and can be enabled/disabled by the operator via configuration settings.

    I thought the L4S drafts were experimental, not standards-track:
    
    https://tools.ietf.org/html/draft-ietf-tsvwg-aqm-dualq-coupled-08
    https://tools.ietf.org/html/draft-ietf-tsvwg-ecn-l4s-id-04
    
    Was there one that's standards track?
    
    Thanks and regards,
    Jake

            I was unaware of this notice, and as I note, it's only march...
            
            Using up the last ECN bit in this way, for the sole benefit of the cable
            industry, strikes me as a poor standard for the internet.
