There are also some other related topics that might be considered
on how this should develop long-term:

1. How important is it to support host distributions that are not 
listed as supported? Not limited to uninative it can be painful
adding support for new distributions to stable branches.

2. Does using uninative by default bring enough benefits to outweight 
the problems with new host distributions, or should it become 
non-default in master?

The sum of the two points above is especially problematic:
"re-use of native shared state artifacts across different host 
distributions" is a more exotic feature, and effectively supporting
this for unsupported host distributions is the problem here.

3. uninative is so fragile because it tries to fix the C library
only. A lot of problems with host distributions (not limited to
uninative) would go away if one host distribution would be picked
and provided as container for people who are using other distributions.
