Could someone tell me if the fastmap feature in ubi is stable for use in production?

Hi experts,

I have found the below link in the linux-mtd website explaining fastmap feature in ubi.

Our project uses large nand flash and I found that fastmap can reduce the ubi attach process to the time we want. Our concern is, since it is an experimental, is it stable to use in our project? Are there any reported issue of this feature?Our biggest worry is that can it possibly brick our system during the boot up process.  

Best Regards,
