Native Schannel TLS stack of #Windows was so unreliable it got axed from #curl:
* Never worked reliably under real‑world loads.
* Quirky, cumbersome API/architecture that broke integrations.
* Zero developer interest—nobody tested or maintained it.
* Pure maintenance drag with no real benefit.

So #Microsoft again shipped a built‑in that nobody uses, and projects ditch it entirely in favor of better third‑party alternatives.

I hope that by now most readers of my blog have understood that curl, and libcurl specifically, is an architecture with a transfer core with a set of different backends plugged in. Backends powered by different third party libraries.
