[dns-operations] [Security] Glue or not glue?

[Stephane Bortzmeyer]

A new edition of the DNS security guide by ANSSI (French cybersecurity
agency) recommends to prefer delegations with glue because glueless
delegations "may carry additional risks since they create a
dependency". Is there any other "best practices" text which makes such
a recommendation?
