I'm trying to mirror the Web and Scripting module repo onto a SLES12 system:

Is the smt-repos (from smt-server package, correct?) command still the correct command to mirror a SLES repo on SLES12?

I can't seem to find a version of the smt-server package for SLES12, is the recommended approach to use the SLES11 SP3 package?

Once that's in place mirroring the repos should be as simple as running this, I assume:
for REPO in SLE-Module-Web-Scripting12-{Pool,Updates}; do
  smt-repos $REPO sle-12-x86_64 -e
