Well, a screenshot might be a good idea to demonstrate what you're
speaking about. A fact of life is that the current Postscript hinter
(used for Type 1, CID and CFF fonts) is slightly buggy and less
advanced than the current auto-hinter. In many cases, it will produce
"inferior" text. There are even issues with certain fonts that contain
"strange" hints, or normal ones (like edge snaps) that are currently
ignored.

In other words, the Postscript hinter needs more work, and this could
be an explanation. Do you have code to show that FT_Outline_Decompose
doesn't work correctly though ?

ROTFL :-) I'd like to see that (hint: I know OCaml), though I doubt
it would compile within the FreeType code base.

The effort isn't finished, unfortunately, there are still
room for improvement :-(
