Seems pretty decent, though I don't know much about low-memory
implementations.

Mike Hamburg's STROBE manages to pack all its symmetric crypto into a tiny
space (see Table 2 in below), it will be interesting to see whether
Noise+Strobe could reduce that even further (by replacing AESGCM and
BLAKE2b with Keccak).
