The author of
http://sourceforge.net/projects/freecelljsolver/ told me he tried
implementing this option (which is available in PySolFC's interpretation of
the Freecell rules) in his solver, and that he could not find any initial deals
which were impossible without it and for which adding this feature made them
solvable. Here is the exact quote from the E-mail:

Shlomi,
I notice that pysol allows moving cards from home cells, but couldn't
find another reference that have that rule. I do have the impression
that only the top card of the home cell can be moved down, for only once
though, but could not find the source of that.
According to my solver results, with or without this rule does not seem
to affect the solvability of a board.
Do you have more information on this?
Also, I think it is very inconvenient that pysol does not have Microsoft
equivalent board generation - how hard is that?
