Does a linux implementation of this exist? It looks promising...

Not that I know of. Contact the authors and they may be able to help.
Microsoft is more open source friendly now, but obviously all the research is
on Windows implementation.

Hi Dave,
some brief information regarding HyStart++ on Windows:
https://techcommunity.microsoft.com/t5/networking-blog/algorithmic-improvements-boost-tcp-performance-on-the-internet/ba-p/2347061
https://datatracker.ietf.org/meeting/113/materials/slides-113-tcpm-draft-ietf-tcpm-hystartplusplus-04-00
AFAIK, there is no Linux implementation for HyStart++, only HyStart:
https://www.kernel.org/doc/html/latest/networking/snmp_counter.html#tcp-hybrid-slow-start
(but I would be interested if there was a HyStart++ implementation for
Linux; also there are several papers about HyStart but not HyStart++)
And HyStart++ should be available in FreeBSD:
https://reviews.freebsd.org/D33035
https://cgit.freebsd.org/src/commit/?id=653cf466f08584c0fd87bc336cdc1db08f0d4434
Best regards,
Joerg

And of course some QUIC implementations have HyStart++, e.g.,

The puzzling thing is turning off pacing in these implementations...
