The version I sent before was faulty. It gave a warning message.
Here it is again:

The following version gives no warning, but it prints an extra empty
staff line.
\score{
\notes {\time 3/2; \type StaffGroup <
\type Staff=treble \notes \relative c''{

This version also produces an extra staff line:
\score{

So if you did \relative \transpose MUSIC then the MUSIC would be read
without any relative behavior?

You already DO have to do \transpose \relative inside a .fly file for
useful behavior, so this would be no loss.
One disadvantage of printing a warning as Mats suggested is that
you'll always see the warning if you use "\transpose \relative" inside
a .fly file.
