Hoi, There are several parts to that question. Typically you upgrade for the benefit of new functionality, security fixes and performance improvements. These are all sound reasons why we should upgrade. Reasons why not to upgrade are prerequisites for the upgrade are not in place, the logistics of it and also the need to retro fit customisations made to the current product.
There are powerful reasons why we should upgrade.. The most powerful to me is the much improved support for UTF-8 and the associated collation. I am of the opinion that the current version of MySQL is holding us back and prevents us from realising much needed functionality. Functionality that will particularly benefit the "other" languages. Functionality that is currently emulated by a hack that is broken by design. Thanks, GerardM

Domas, I assume you're still on this list - can you give us some
background
why we're not on a closer to current release MySQL within the WMF environments?
Upgrading for the sake of upgrading is always a bad idea. The question should also be "why should we upgrade?" not "why shouldn't we upgrade?".
