yeah, meta-yocto could have been better name meta-poky that would have aligned the name
a bit. Its a distro layer much like other distro layers out there on layerindex and then there is meta-yocto-bsp
layers which is much like any other machine layers out there.
a difference to point out is that poky uses the tooling to fudge all layers together and create a single view
and is a leading user of combo-layer tooling provided by OE-Core. Other distros keep the layers intact
slugos e.g. uses git submodules to maintain its layer setup. angstrom has home-brew toolings and so on an so
forth. Both approaches have its own merits.
