FWIW, the "S" flag means:

  Do not apply transformation to symbolic link targets.

(see https://www.gnu.org/software/tar/manual/html_node/transform.html
-- it's a bit hard to find in the docs ...)

In my use case, this allows me to build a dist archive from my main
source directory, adding a directory level in the tar, while leaving
symlinks unchanged:

  --transform='s|^|$(DIST_NAME)/|S'

This is not a fully general solution to the problem as I described,
and it may or may not help for your use case.

Viele Grüße,
