I understand this but I ask for more... I think the hacks brake the software stability. So if possible add joomla 1.5 templating system with a plugin is a good compromise for interoperation between the different CMS. So I can use the new joomla 1.5 feature and don't brake the compatibility with the other CMS. Further, If they add the template hack with a plugin we can personalize the CB layout and don' brake the CB stability. This in my opinion.
Just a funny idea, but why don't you change the template you use for your profile? There are 5 templates included. If you don't like them, make your own
