The typical Yocto user starts with whatever prehistoric Yocto release 
came with the BSP distribution for the reference hardware, and then 
develops a new product on top of that.

I would not be surprised if someone will have the initial Yocto 2.7
release, but uses the latest from the corresponding  meta-openembedded 
branch on top.

Thanks a lot for this.

I'll take care of getting these removed from meta-openembedded.

python3-docutils is ouch, since this problem is also in dunfell.

On a more positive note 0.16 is already in OE-core in the initial
Yocto 3.1 release, so removing it from meta-openembedded will only
be like a 0.15.2 -> 0.16 upgrade for some users but cannot result
in losing the recipe in weird layer combinations.
