We don't want to tie hob to meta-yocto, no. The solution to this problem is to 
have Hob understand when removing a layer is removing the DISTRO selection 
that a user currently has made and warning them about it; if they respond in 
affirmative then DISTRO can be set to empty (or we can allow them to select an 
alternative, perhaps - something for the designers to consider). Fortunately 
since DISTRO points directly to a file in conf/distro/ the detection part is 
pretty easy to implement.

Cheers,
Paul
