Apple has a precedent. The Carbon API was so named because "all lifeforms will be based on it". The Cocoa API was so named as an alternative to the Java API, at one point a major pillar for Mac OS X before Apple discovered people preferred to learn Carbon/Cocoa than bother with Java.

Marzipan, if the name does stick, could be "the icing on the cake" that brings iOS developers to the Mac. It seems as though Apple has been spending the past twenty or so years preparing a small bakery.

We patiently await for an updated version of discoveryd to be reintroduced into macOS, codename Tea-and-Biscuits.

This is an internal code name for something that has not been publicly released.

Agreed. I understand unexpected brands for consumer facing products – Apple and Blackberry come to mind. But for a tool / library meant for developers, it seems a bit over the top.

To make marzipan structurally sound requires adding too much sugar, which spoils the taste.

It contains very little almond. Instead, it contains white beans as its cheap and a good emulsifier.
