I agree with both of what you write, but that doesn't solve the problem,
since you can't forbid people allowed to upload a key. I have got almost
all signatures from people I met personally -- but still you won't have
most of the certificates that signed my key ...

I think Robert's proposal (at least this one about hiding unknown
signatures) is very reasonable.
