For some "extremists" storing the text in the database is bad. Why not explore the file storage for text?

Several other wikis store page text in the db. I think mediawiki is one good example.

I don't think modern dbs have much issues with such data. It's also convenient as a db backup will capture all the wiki data incl text, not just page links or todos.

However, considering other page data storage formats is not a bad idea if you have good reasons to do it. I don't think "extermist" preference is good enough a reason. ;) Performance, generality, better search, etc might be. But I think it'd be good to have a design, perf and usability goals in mind for making such a change.
