TEN-T network has core network, which is the most important and
comprehensive network, which is less important. 
There are also other DK roads in Poland, which are even less important. 

So only the core network can be `trunk` coz it is the most important by definition and everything else is next most important

Those are questes from OSM official documantation. 
You can't outvote that. 

Really, you didn't raise any new points, you just want everything to be trunk, coz there was a vote, on rules that were being changed while people were already voting. 

But yeah, i know you don't care, coz you like red road on carto just to fell better ;]
