I don't know.

While it is more than 10 years ago, I seem to recall a lot of stuff on 
Mutopia where there are LP files to use are from much older than 2010.

I think at the very least we should perhaps 'flag' anything (either as a 
warning or as an error) for users that might have needed to convert 
something that we have removed because of backward compatibility if they 
tried to use such a convert-ly file. Rather than look like it has worked 
until they try to compile it with the later code and then get an error 
and open a bug report (if you see what I mean).
