Yes, that's right.

That is true for the distribution versions, but there may be developers
doing some compiling themselves using latest.

I think it would be ok to start the process of removing python2 from
DPDK...but...there probably needs to be some deprecation notice and time
to allow people upgrade or raise any concerns.

At least, I see some test reports for LTS coming back as run on older
RHEL/CentOS 7 versions (probably master too), so some people will need
to schedule upgrades.
