Follow-up: do you mean remove python2 from HOSTTOOLS, or the recipe
from oe-core?

$ bitbake -g world
$ grep -- '-> "python"' recipe-depends.dot
"kernel-devsrc" -> "python"
"ltp" -> "python"
"meta-world-pkgdata" -> "python"
"packagegroup-core-tools-profile" -> "python"
"packagegroup-core-tools-testapps" -> "python"
"packagegroup-self-hosted" -> "python"
"perf" -> "python"
"python-nose" -> "python"
"python-numpy" -> "python"
"python-scons" -> "python"
"python-setuptools" -> "python"

Nothing depends on the python-* in core, we can ignore the
packagegroups, so that leaves kernel-devsrc, ltp, and perf. Also
u-boot uses nativepython.

HOSTTOOLS is more complicated and there's still plenty of pieces that
use host python.  I've an old poky-contrib:ross/nopy2 branch that
fixes a few more users of host python2 that needs rebasing and
retesting.
