Ah yes, that's a good idea. I've tested the mscrypto backend, and it
seems there the this flag doesn't work there as expected either:

So I understand that:

1) It works properly if the relevant --trusted-... option is used.
2) It fails when --insecure is not used, though it complains about "key
is not found", not NSS-style "certificate verification failed".
3) It still fails with --insecure -> unexpected.

I'll try to find time to look into what's the problem there & fix it
unless somebody beats me to it. :-)

Miklos
