I have some doubts about ACLs containing "by users" and the term

It means anyone who has successfully authenticated, by any means.

It seems that slapd grants access with clause "by users" but I feel this
is wrong. I'd prefer if "users" would mean fully-identified clients
mapped to a real entry.

No. Such a restriction would prevent distributed authentication from ever

The downside of not being able to be able to specify authenticated DNs vs DNs that actually map to an entry in the database is that for some things (like SASL/GSSAPI setups) it makes the "users" value completely worthless, as any kerberos principal in the KDB that connects to the ldap servers is considered a "user". Thus I had to rework all my acls to avoid ever using the "users" concept when it would have been quite useful (and had to resort to sets instead).
