I think the statement in the manual still applies; it’s only that the message was removed for some reason. (just guessing)
I would reword the paragraph by making clear that slowing Anki is not the issue at all. - even at 1000 decks. Or simply change the word ‘several dozens’ to ’ several hundreds’.
There are many variables, computer performance, SSD versus hard drive, network connections, how the cards are constructed, number of tags and so on and so on…
I have tweaked the wording a bit, but I would still not recommend you go wild with thousands of decks.
