While the Buddha doesn't to my knowledge say "This is vipassana practice..." , He does seem often to indirectly refer to insight practice .
SN35.165 (10) Abandoning Wrong View
Then a certain bhikkhu approached the Blessed One … and said to him: “Venerable sir, how should one know, how should one see, for wrong view to be abandoned?
Bhikkhu, when one knows and sees the eye as impermanent, wrong view is abandoned. When one knows and sees forms as impermanent … eye-consciousness as impermanent … eye-contact as impermanent … whatever feeling arises with mind-contact as condition … as impermanent, wrong view is abandoned. It is when one knows and sees thus that wrong view is abandoned."
Same for abandoning of self view SN35.166-167
Abandoning of wrong views doesn't require the "a whole bunch of books" approach. A thorough anicca meditation can do that.
I am sure that Mahasi or Goenka like practice may heve been implied above. There are many passages in SN that could be interpreted as "labeling" of some sort.Ignorance needs to be abandoned. And how? By knowing and seeing faculties as impermanent
"Ignorance, bhikkhu, is that one thing through the abandoning of which ignorance is abandoned by a bhikkhu and true knowledge arises.
Bhikkhu, when a bhikkhu knows and sees the eye as impermanent, ignorance is abandoned by him and true knowledge arises. When he knows and sees forms as impermanent. When he knows and sees as impermanent whatever feeling arises with mind-contact as condition … ignorance is abandoned by him and true knowledge arises." - SN35.79(6) BB translation.
"If a monk, while keeping track of arising & passing away with regard to the eye-faculty, becomes disenchanted with the eye-faculty; if, while keeping track of arising & passing away with regard to the ear-faculty... the nose-faculty... the tongue-faculty... the body faculty... the intellect-faculty, he becomes disenchanted with the intellect-faculty; and, disenchanted, he becomes dispassionate; through dispassion, he is fully released; with full release, there is the knowledge, 'Fully released'; he discerns that 'Birth is depleted, the holy life fulfilled, the task done. There is nothing further for this world,' it is to this extent that one is consummate in faculties."

"when a bhikkhu knows and sees the eye as impermanent..." , here it may be implied that one labels the eye [and others] as "as impermanent". And satipatthana sutta may imply labeling...
Just few thoughts...
IMHO.
With metta,
