I remember some "glidesort" also being introduced. Wonder what happened to that

From what I understand as I skimmed over the stable sort analysis (https://github.com/Voultapher/sort-research-rs/blob/main/writeup/driftsort_introduction/text.md), it lost out against driftsort.

orlp invented PDQSort and Glidesort. He collaborated with Voultapher on Driftsort.

Driftsort is like a successor to Glidesort.

Glidesort had some issues that prevented it from being merged into std, and which are addressed in Driftsort. IIRC it had something to do with codegen bloat.
