you're right, if it was only for my use and I already installed it with mysql and it was very fast to install and begin to use, excellent application. But, my suggestion is to create more compatibility for the product, I can see in this table http://en.wikipedia.org/wiki/Comparison_of_wiki_software that few have DB2 support, so if it is not very complex I would like to work with it.
Nowaday, webapps use either Postgre or MySQL because they are fast, reliable enough. People tend to start using Sqlite too as it is even lighter and need close to no configuration. When using them with PHP, you are just using an open source environment that also comes with Apache and rarely offer any proprietary database format with it.
Some people implemented Oracle and MsSQL support because they already use those in their company. This way they will get support from their usual DBA, handle back up and use the same support contract.
As for DB2, the last time I heard about it, it was clearly not for a webapp. It was used on IBM z/OS which run on the IBM Mainframe. The kind of "servers" which have decade uptime and hold your bank account (and other interesting things).
To conclude, probably nobody is going to use MediaWiki with a DB2 backend. But you can still implements it as an exercice :o)
