No surprises comparing this file (sha256sum d05062052be4dd6fbaeac5f17598e52f7ad545f9f938acefaf7067ecce1d7b5a) with the blockchain. I hope posting these verifications is useful to others.
I'm doing it this way because it's faster to stream data out of bootstrap.dat rather than pulling the data out of bitcoin-cli. So I can generate the sha256sum from the client once for a given range, and use it to verify that the data hasn't changed. Future updates just need a checksum out of bitcoin-cli covering the new parts. If anyone's interested in the blockheight program, I can publish it.
Blocks 0 through 295000, bootstrap matches blockchain:
$ ./blockheight -e 295000 d83ea8602fb5d2ad863afc7fae1b25794bc7da37d2da642e6aca15f2ad19d9e9 -
$ for((i = 0; i < 295001; i++)); do ./bitcoin-cli getblock `./bitcoin-cli getblockhash $i` false ; done | sha256sum

Blocks 295001 through 313000, bootstrap matches blockchain:
