The particular case we are discussing is a good example for both items: convert_ACM_siggraph() in lyx2lyx does currently delete document contents without telling the user
It told the user with a red note at the beginning of the document. It also explained what happened and how to proceed.
(our standard way would be to convert unsupported styles into ERT, possibly commented),
This is not very sensible in my opinion in this case because these information are now not only unnecessary but even unwanted because they use now a new system for the submission info. A pointer for this was given in the note lyx2lyx added.
and frustration has already been voiced on the list (not by me, I am not frustrated).
I reverted siggraph stuff now. Please do me the favor and don't require to introduce another fileformat change. The probability that a user used LyX 2.2git to write a real ACM submission is almost zero thus I won't make it more complicated that it is.
thanks and regards Uwe
