[Mediawiki-l] Liquid Threads to be integrated into MW 2.0?

Hi

I'm in the process of installing MediaWiki and am interested in using the Liquid Threads extension to replace the standard talk pages:

http://www.mediawiki.org/wiki/Extension:LiquidThreads

It states on the extension page that this extension is being developed with the aim of being integrated into MW 2.0 - is this an aspiration of just the extension developers, or also of the MW developers themselves?

I'm concerned about what would happen if development on this extension stopped one day, and the extension then became incompatible with future versions of MW. If I had to uninstall the extension, does any one know what would happen to the discussions up to that point?

Thanks

Derrick
