Indeed!  I was curious, so I built the "TLS client" example in the 
rustls repo.  It compiles in the following 32 crates:

aho-corasick, atty, base64, cfg-if, ct-logs, docopt, env_logger, 
humantime, lazy_static, log, memchr, mio, once_cell, quick-error, quote, 
regex, regex-syntax, ring, rustls, rustls-mio, sct, serde, serde_derive, 
spin, strsim, syn, termcolor, thread_local, unicode-xid, untrusted, 
webpki, webpki-roots

(Note things like webpki are used in the example.)

A `--release` build comes to 6,844,552 bytes. So no, not small.
