I can probably find the email thread (or maybe it was a GitHub comment on my proposal for params), where you said, quite definitively, that this was *not* a general-purpose mechanism but rather a way to expose the necessary internals for opaque objects like RSA keys.

What changed your mind?

Perhaps not surprisingly, I agree with Shane's assessment and am strongly opposed to the project foisting this on everyone at this time.  @DavidBen, your thoughts?
