Debian still having trouble with merged /usr

It's been what more than a decade now since the initial push to clean this artifical mess up on the core/baseOS level which should be way more than enough time for downstream distributions to adapt.

There is literally no technical reason to support systems with split-usr and supporting the split-usr mode makes both code and documentation more complicated for upstreams ( it adds to the CoD for projects ).

Upstream will and should at this point in time close any such issue with wontfix and consumers of components that make up the core/baseOS layers should rather expect that split-usr mode is not supported or no longer supported and upstreams will drop this without hesitation or as much as a warning at this point. ( not that such warning would ever be visible to anyone other than the person building the software anyway like [1] )
