Luma Home WiFi and others, OpenWRT official stance on Mesh / AP vs Official "router" images?

Is it possible(I haven't seen any yet) that OpenWRT will split out certain images as more mesh / multi-wifi projects are supported into Mesh/AP images and full/default/base router images?

Does anyone have a list of packages for 21.02 for optimal hardware packages and settings/config for mesh use(s/r)?

Are there any I don't need from the default list here if I am just going to use it as an AP and possibly add another device to the LAN port?
