I think they are not propagated currently for convenience archives.  As
to whether they should, I'm not sure.  I remember that this has been
reported before.  I also remember that the issue has not been entirely
noncontroversial.

Somebody would have to dig in mailing list and commit history (of the
Libtool project) to find out for sure.
