Yes, but the issue is bugs.

If someone fixes (or introduces...) a bug in a primality test, then I might
recover a different key.  This doesn't happen if I generate and key the
private key.

If I lose my system and I install a new system, the odds of new/patched
software compared to when I first generated is high.
