UI Plugin Upgrades

UI Plugin Upgrades

<span style="font-family: trebuchet ms;">It sort of implies that jQuery UI 1.0 will upgrade all of the includes plugins at once with 1.0.1 and 1.1 etc. 
Is this the plan?  Or will sub-plugins be upgraded independently?
or both, where the UI is really a periodic "tested/approved" roll-up?<br style="font-family: trebuchet ms;"></span><br style="font-family: trebuchet ms;"><span style="font-family: trebuchet ms;">Thanks,</span>
