The blurb is directly from RFC7030. We reiterate it here to point it out as a best practice and then we present a potential deviation from it for constrained environments. 

To avoid this confusion we can rephrase it as 

    As discussed in Section 6 of [RFC7030], it is 
   "RECOMMENDED that the Implicit Trust Anchor database used
   for EST server authentication is carefully managed to reduce the
   chance of a third-party CA with poor certification practices
   jeopardizing authentication.  Disabling the Implicit Trust Anchor
   database after successfully receiving the Distribution of CA
   certificates response (Section 4.1.3 of [RFC7030]) limits any risk to
   the first DTLS exchange." [...]

Rgs, 
Panos

Section 10.1:

"It is also RECOMMENDED that the Implicit Trust Anchor database used
   for EST server authentication is carefully managed to reduce the
   chance of a third-party CA with poor certification practices
   jeopardizing authentication."

This strikes me as a slightly odd use of normative language (what are the exception cases when the trust anchor database should not be carefully managed?).
