I'm not sure you understand how WSL works: it's just the native `curl` binary for whatever Linux distro you're using in WSL. On both Ubuntu and OpenSuSE, which are the two I have installed, --cacerts works as expected, because of course it does.

Separately, Microsoft bundles curl.exe as part of Windows since somewhere in the later Windows 10 or early Windows 11 releases, I forget which. This also appears to be honoring --cacerts.

So no, this seems to very much be an Apple problem.
