I also believe it is too early to attempt the work of making a common API.

    Hi,

    Recent work shows that different implementations behave quite differently:
    https://urldefense.proofpoint.com/v2/url?u=https-3A__doi.org_10.1145_3405796.3405828&d=DwIFAg&c=5VD0RTtNlTh3ycd41b3MUw&r=C0sUo-LFNBaYfyoaCsf6TA&m=J-cKq53K_uZRmp7yK197soYnAI5fVyG0TT-hNubky1Q&s=eHCgEpYrCyhx-s1DW979BYYTi65WBltnE1BAfaO0hak&e= 

    Takeaways of related academic work on QUIC is increasingly becoming a 
    function of which implementation(s) was(were) used to perform the study.

    It is tricky to study QUIC behaviour for application workload(s) at the 
    moment since implementations are so divergent that rewriting the application
    using X-different implementations and then repeating the experiments to 
    converge to a conclusion is the only choice left. However, QUIC is also a
    moving target where snapshot views quicly ;) loose value with time, 
    demanding a longitudinal view which makes it even harder.
