On a Windows Server 2019 share with symlinks:

    C:\shares\data> dir
    ...
    12/16/2019  08:04 AM    <SYMLINKD>     DIR [sub\dir]
    12/16/2019  08:04 AM    <SYMLINK>      foolink.txt [sub\dir\foo.txt]
    ...

Mounting without cifsacl kind of works (still missing mode bits):

    # mount //nuc.test/data /mnt -o username=user1,password=user1,vers=3.0
    # ls -la /mnt
    total 3148410
    ...
    l---------  1 root root          0 Dec 16  2019 DIR -> sub/dir
    l---------  1 root root          0 Dec 16  2019 foolink.txt -> sub/dir/foo.txt

Mounting with cifsacl (with working idmap):

    # mount //nuc.test/data /mnt -o username=user1,password=user1,vers=3.0,cifsacl
    # ls -la /mnt
    ls: cannot access '/mnt/DIR': Operation not supported
    ls: cannot access '/mnt/foolink.txt': Operation not supported
    ...
