Certainly there is interest.  The debugging should start in libinterp/corefcn/file-io.cc.  There you will find the DEFUN for fread.  This calls out to do_fread() and I think that's where you should start hunting for a solution.

Is there still interest in this topic ? I've met the
inability of GNU/Octave to perform a ubit1 fread (which
works in Matlab) ... am willing to have a look at it if no
one has so far.

Changing the Item Group to "Matlab Compatibility".

An easy workaround for the 'bit24' option is 'int24' which is supported.
