For what it's worth, I've encountered very similar attitudes over the
years in other environments. A good example is the digital library
world; both regarding access to digital collections and online access
to OPAC data, it was quite common to see Z39.50 search protocol access
to the full collection, but accompanied by a rather cautious
reluctance to also offer a simple data dump of the entire thing.
Pointing out that you could do this via repeated Z39.50 searches was
rarely helpful, and seemed more likely to encourage the search
interface to be restricted than for data dumps to be made available.
But hey, times are changing! I think it's just a matter of time...
