Hi Inigo -
Some of your comments indicate a basic lack of understanding of past and 
current network systems. I'd like to correct a few of your points here. 
Please see comments inline.

Thanks -

Metacat was perfectly capable of distinguishing between revisions. FCE 
had a ad hoc definition of "data set revision" which was inconsistent 
with what the rest of the network was doing. Unfortunately, their 
practice didn't get aligned with the rest of the network till after the 
first DataONE submission. That's why FCE datasets appear the way they do.

I disagree. data that are in repositories should have undergone 
sufficient review to be appropriate for the public before it was 
submitted. There exists a manual process for removal (for rare cases).

Removing datasets is not a common occurrence, so should not be a trivial

Identifiers, if they were carefully assigned originally and in a robust 
system, were not retired. See any SBC dataset in PASTA, and you will see 
that the same identifier was used for previous revisions in Metacat. I 
know this is true for at least half the sites as well (GCE, MCR, HFR, 
VCR, AND, NTL among others).

This is true, and has always been how our systems work (metacat and pasta).

It will be archived (not erased), so that if someone has a link, it will 
still work
