An idea to help with detection of module incompatibility issues

I hope this is the right place to post this. I have spent the last couple of years working with Drupal, first in 5 and presently in 6. Quite often, in the course of development, I run into problems of modules not behaving as they should, and spend a large amount of time reading over issue queues and following leads from one to another. I have a feeling I'm not alone here ;o)

Many times the cause of the problem is tracked down to an incompatibility between modules, which led me to the following idea:

A new module which automatically uploads a user's current installed module list to a field group in their drupal.org profile.

This would be a good start in that we could manually go and have a look at that list and see if anything rings a bell with us. But we could do more:

The module list could be intelligently cross referenced (by drupal.org) for users with the same issue.
A report could be generated showing the similarities of installed modules between the users with the issue in question.

Results could be improved by optionally filtering out module combinations that have large user bases (cck, views, panels etc)

Results might be further improved if modules had a compatibility ranking, based on the number of incompatibility issues they have had and the installed user base.

It might also be useful if there was some kind of module incompatibility status page automatically updated by the module maintainer selecting an incompatibility status or tag in the current issue.
