A Potentially Useful Property - Last Informative Proposal

As writing systems can be quite complex, there is often useful
information about a character that cannot be found in the Unicode
Character Database or the Unicode Standard, but is present in one of
the proposals leading up to its inclusion.

To this end I have half-jokingly suggested that it would be useful to
have an informative numeric property 'last informative proposal'. A
non-missing value xxxx would indicate that the last proposal to contain
useful information about it would be held as
http://std.dkuug.dk/jtc1/sc2/wg2/docs/nxxxx.pdf .

Now, there can be problems with establishing the value - it may be
require a judgement call as to when revised proposals started to
provide less useful information. There are also subtle variations in
the URI. Now, I don't seriously expect the Unicode Consortium to take
on the task of setting up such a database, but are there any publicly
available databases with such information or a reasonable
approximation? A poor approximation - but a lot better than nothing -
is the derived age property which records when a character entered
Unicode. One problem with using a search engine is that the name and
code point proposed for a character can change during the encoding
