Yes, this is intentional.
In the past, this approach has caused governments who tried to censor connections to the Tor network to miss these bootstrapping avenues.
It's certainly not a robust trick, but it has few downsides, so I think it's reasonable to keep it in place.
(It does, every so often, result in a confused researcher who thinks she has "blocked all the Tor relays", yet is surprised when Tor Browser bootstraps anyway. To me this presents a good opportunity to increase understanding of how censorship works and doesn't work.)
