In a way 'true' has been dropped becauswe it doesn't do anything and I 
will likely remove that check completely (as \mag is also gone, although 
the performance hit for scanning true is neglectable in luametatex).

Anyway, I'll check it. Is anyone still using this "true" actually?

I don't check github, it's mostly there for the compile farm and 
intermediate testing (e.g. math stuff) so sending me a mail is ok. When 
there is some serious issue a mwe to the list is good enough.
