This doesn't mean that BibTeX is a bad basis. The set of types and  
fields is limited, though.

Since renderings of bibliography don't show the type of the reference  
usually, having to use 'misc' for almost everything isn't a practical  
problem although it is aesthetically displeasing.

The set of fields is more of an issue, but it can be fixed by  
inventing more fields--it doesn't mean the whole base solution needs  
to be discarded. Fortunately, having custom fields in .bib doesn't  
break existing pre-Web, pre-ISBN bibliography styles. I've used at  
least these custom fields:

key: Show this citation pseudo-id in rendering instead of the actual  
id used for matching.
url: The absolute URL of a resource that is on the Web.
refdate: The date when the author made the reference to an ephemeral  
source such as a Web page.
isbn: The ISBN of a publication.
stdnumber: RFC or ISO number. e.g. "RFC 2397" or "ISO/IEC 10646:2003(E)"

Particularly the 'url' and 'isbn' field names should be obvious and  
uncontroversial additions.

Do you have an example? (I've never used the other formats.)

In practice, those problems have already been introduced. For some  
reason I don't understand, there's an existing pattern of calling a  
field 'doi' but putting an absolute URI in the value. (As opposed to  
using a field name 'url' or a value that contains only the DOI- 
significant part.)

Problems of this nature haven't stopped the WHATWG in the past. :-)

When you are referring to THAT document, you generally want the names  
of the authors--not their full business cards. Therefore, vCard is an  
overkill, and conversion to .bib is more useful than conversion to  
vCard for this use case.

This would make conversion to and from the dominant bibliography  
format (.bib) more complex. Furthermore, there's a risk of a GIGO  
effect where the conversion can't be done algorithmically. (IIRC, you  
can't algorithmically map a .bib author name to the vCard name  
structure without a huge dictionary of names.)

Why is typing even needed except for separating articles from  
compilations?

How are these useful for conversions to and from the incumbent format  
(BibTeX)? (Only BibTeX is supported by all of Google Scholar, the ACM  
Portal, Stanford Spires, NASA ADS at Harvard and Citebase.org. The  
three last ones being databases that arXiv seems to delegate to.)
