This is, of course, a chicken and egg thing. The reason why a lot of MARC data remains inconsistent is precisely because it is not being used for finding or display.
Anyone who has worked with a faceted search application has seen this in action. As soon as you aggregate subject headings, genre designations, etc., into facets you begin to see all kinds of data problems that you never noticed before because they are scattered among thousands of records that previously could only be viewed individually.
Of course, fixing bad or inconsistent data is probably an order of magnitude easier than adding data to records after the fact.

I think Dublin Core XML is an excellent attempt at what you're talking
about if you want to consider it a bibliographic data format, which I
guess could be one of its many uses.
I know that a large percentage of the data in our MARC records is not
being used for finding/gathering or even display, so in that case, what
good is it? There is a lot of richness in those records, but it's so
all-over-the-place that whatever value it might have had gets killed by
all the inconsistency. In my experience, good, consistent metadata that
captures the essence of an object is more useful than highly-detailed,
inconsistent metadata (which all highly-detailed metadata tends to be)
in a fine-grained element set.
I think there may be a cultural element to this as well, in that IR
people think of metadata in terms of its utility for IR purposes (at
which DC tends to be extremely practical) and catalogers think of it as
a thorough-as-possible description of an object (at which DC is quite
