I think the current approach (return the same value as ' does) is
better, for the same reasons that it is better to make these words
tickable and interpretable: It's more uniform, it's more traditional,
and it's easier to program for (no special-casing for 0 is necessary).

If you NAME>INTERPRET or ' IF, you get the xt for the compilation
semantics of IF, and I think that's also the case for all the other
remaining compile-only words. Likewise, if you text-interpret IF (in
either state), the text interpreter will perform the compilation
semantics (so they have all become immediate in every sense, not just
"immediate-but-..."). Example:
: foo [ if ] ." foo" then ;
:1: warning: IF is compile-only ok
0 foo ok
1 foo foo ok
: bar [ ' if execute ] ." bar" then ;
:4: warning: IF is compile-only ok
0 bar ok
1 bar bar ok
