I mean it doesn't look like it should be a regression. If it is, it is some
magic foo going on. In particular between 5.13 and 6.0, the source code for
sage.interfaces was only touched by trac #15440 (some maxima funkiness),
and SAGE_EXTCODE wasn't touched (it hasn't been changed for over a year by
this point).
Or do you mean that you think this has always been

A work-around (not a proper fix) is to mimic the standard interfaces
initialization, i.e.
-octave = Octave(script_subdirectory='user')
+octave = Octave(script_subdirectory=None)
and similarly for the other optional interfaces that seem to get very
little attention.
