A reference nit I happened to notice: it looks like the Hystart reference here seems to have a few issues:
[HyStart] Ha, S. and I. Ree, "Hybrid Slow Start for High-Bandwidth and Long-Distance Networks", DOI 10.1145/1851182.1851192, International Workshop on Protocols for Fast Long-Distance Networks, 2008, <https://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.517.2701&rep=rep1&type=pdf>.
(1) that reference is listing a URL that no longer works.
(2) that reference is referencing a 2008 paper about Hystart when there is a newer paper from 2011 that might be better to reference; the 2011 paper is referenced by 8312bis as follows, and includes a working URL:
[HR11] Ha, S. and I. Rhee, "Taming the elephants: New TCP slow
start", Computer Networks vol. 55, no. 9, pp. 2092-2110,
DOI 10.1016/j.comnet.2011.01.014, June 2011,
<https://doi.org/10.1016/j.comnet.2011.01.014>.best regards,

The IESG plans to make a decision in the next few weeks, and solicits final
comments on this action. Please send substantive comments to the
last-call@xxxxxxxx mailing lists by 2023-01-25. Exceptionally, comments may

Abstract
This document describes HyStart++, a simple modification to the slow
start phase of congestion control algorithms. Traditional slow start
can overshoot the ideal send rate in many cases, causing high packet
loss and poor performance. HyStart++ uses a delay increase heuristic
to find an exit point before possible overshoot. It also adds a
mitigation to prevent jitter from causing premature slow start exit.
