[racket] Snapshot builds

I recently ‘discovered’ (thanks to a tweet from @dkvansnickajr) the snapshot builds for ARM6 built on Raspbian. 
Previously I’d been recommending people try out Racket on RasPi via the source+built packages route, but realise they might baulk at the build times and this other route seems very attractive in this respect. Can I just sanity-check that this new approach is sensible?

Thanks.
