Please don't recite what i wrote in a distorting way.  I said nothing of 
what you imply i said above.  You are free to ignore what i said or 
interpret it for you as you like but you are not free to present a 
distorting interpretation as if i actually said that.

I am aware that that the analysis and suggestions i present are often 
very brief and sometimes difficult to understand - when i say something 
like "external IDs [...] will never scale on a level of hundreds of 
millions of features in the end" you will only be able to understand 
what i mean if you approach the subject with an open mind and analyze 
the same scenario questioning any preconceived assumptions you might 
have about it.  But i have no intention pressing anyone who is not 
ready for it to do that.

I have no real problem with that either - just like i have no problem 
with people keeping adding is_in tags.  As said i would advise against 
it but we have the freedom to use any tags you want and i firmly 
believe in that.  You can question if this freedom applies to 
non-verifiable tags but i am not niggling here.  Automated edits 
adding/modifying wikidata tags are a different subject of course but 
that is not the topic here.
