Well, I could imagine some potentially relevant cases:

1) Necessity to work with a closed source unit compiled with that version
(or unit to which the original sources are lost, which is almost the same
;-) ).

2) Code using lots of assembly and expecting the original calling
convention (this falls into your category of "implementation details", but
it's an understandable one if it involves large amount of code which would
need to be not only modified but possibly also debugged thoroughly because
there are more differences than just the way of passing variables - in
particular ebx needs to be saved). Although in that case 1.0.10 should be
a better option than 1.0.6 - unless the original poster has 1.0.6 only and
not 1.0.10 (in the situation when we do not offer this version for
download any longer, but I could imagine that finding both would be still
possible).

Obviously, these are just random shots and pure speculation - the poster
clearly stated that he didn't want to disclose the reasons.
