Would it make sense for IPB to eventually go fully modular? Having alot of functions is nice but not everyone needs them and certainly having too much script can slow down the site.
If IPB gets many more add-ons (ie WYSIWYG) would it not then make more sense to have a core IPB with the plug-ins added as needed?

Plug-ins..
Mail Room
WYSIWYG
Calendar
etc...
