I consider the support still to be in beta, unless there are some reports of successful placements using these programs, although I've read in several test files successfully.
Note to KiCad users: The current version of KiCad allows you to put spaces to component value. The KiCad generated .pos file is space separated, and the field width can change. These don't fit together, and this will change in a future version of KiCad. So, spaces in values are not accepted without quotes around them (this is how I'm told the KiCad will behave in the future).
