I have been preparing Homebrew and OSGeo4Mac 'taps' for this move and am
now focusing on QGIS 3 formulae, probably starting on Thursday or Friday. I
hope to have everything building and docs completed by the end of the
weekend.

The new formulae will not be hosted in OSGeo4Mac or Homebrew (at least not
until there are stable releases), but in a specific tap for QGIS
development and Travis CI support:

https://github.com/qgis/homebrew-qgisdev

So, look for changes there as things progress. Please contribute or post
bug reports there for those dev formulae or docs, once they are available.
