Block Change Tracking, Incrementally Updated Image Backup and Block Corruption Detection

(Posted this per GoogleGroups few days ago but never found it back in
the group.)

Hi,
We were discussing new RMAN features and touched the topic Block Change Tracking (BCT).
A theoretical drawback of BCT could be of that not all blocks are checked daily for corruption in a BCT setup.

If I combine BCT with Incrementally Updated image copies, in such I way that I will only take incremental backups, how will I find my corrupt blocks?

1 - is there indeed a risk of not being early warned for a bad block when switching to BCT+Incremenally Updated 2 - what would be a wise mitigation of this risk?
(periodical "analyze validate structure"? Take a level 0 once in a
while?)
