This will be to bring in PHP 8.x.x support to Dark Matter. For note: WordPress is considered currently - as of 5.6 - to have only "beta compatibility".
Also worth noting that WP Local Docker and VVV do not seemingly have PHP 8 support yet, so would require a custom environment - or another dev environment tool - for development. At a guess, these two projects will track WordPress compatibility as a timeline for adding PHP 8.
Closing this issue as it was checked in 2.1.8 and the local development environment has been switched to PHP 8.0.x., and no issues have arisen as of yet.
