Well, as I said: in my proposition I did _nothing new_ at all! The 
rendering hints are in the proposition's template. So the process part 
in the tagging dept is already well defined: "if you have some hints 
about rendering, say it here!". What we lack, however, is the part of 
the  tagging interpretation process in the rendering dept.

Default tagging is clearly documented and community voted, but default 
rendering decisions are not even documented and are not even being 
talked-back. They "just happen" in the form of issue tickets and the 
code. So what I like to do is to store those decisions somewhere - and I 
think using already existing tagging dept documentation has additional 
profits for the project in the form of synchronizing both depts docs.

I will say it again, because I feel the fear of mixing everything: 
syncing docs is not about doing everything together! The tagging dept 
decisions may be completely different than rendering dept, but at least 
we can see (a) what are those decisions and (b) why the differ.

Of course they are somehow separate, but the bad thing is they don't 
ever communicate with each other.

If someone is not interested in the second dept, she can easily skip 
this section, but if someone else wants to know how both depts relate to 
each other, he has no clue - he can only look at the map and search 
through the carto tickets in the hope the subject was already discussed. 
The link for the proper ticket in the "Rendering" section would hurt no 
animal. The list of tagging-rendering decisions can help the carto team 
to have broader picture what is done, what should be, what will not be 
done, and what can-be-done-if-something-else-is-done-before.

I hope that sounds less scary. =}
