An iterative improvement would be to, on connection to an "Access 2007"
datasource:

1) Detect whether it is installed, by checking for availability of
   that specific ADO driver (not by checking Windows Installer for a
   specific ID!).

2) If not, have a popup that explains the situation and gives the
   link.

(I believe we have such a pop-up for Java, minus the download link.)

Why would we bundle it? Well, so that things work "out of the
box". Because contrary to Java, this "3rd party package" is a rather
obscure thing for users. Because since it was bundled with most
versions of Windows, users actually never were aware that LibreOffice
was using this third-party package under the hood.

Do the benefits outweigh the disadvantages? You have a point, that's
not clear, maybe even dubious.
