Unlike in Org, in TeX "a\\b" still contains a line break. Besides exotic 
packages and user setups it should just work. After all, during normal 
operation all "%__ORG_EXPORT__" should be stripped by a filter. They are 
just marks where a decision is necessary whether to retain "[0pt]" or to 
remove it.

Stackexchange is for questions, not for discussions and bugs. At certain 
point I was going to ask a question there, I even prepared a draft. 
After that I decided to try a command expanding to nothing and found 
\empty. I was not aware that tabularray uses a different approach to 
parsing.
