Would you be willing to merge nftables into kernel tools directory
then?

Did you miss the part where I explained that people explicitly disable
NFTABLES in their kernel configs in most if not all large datacenters?

If people to chose to disable a certain feature, then that is their own
decision to do so.  We should respect that decision.  Clearly they seem
to have no interest in a better or more featureful packet filter, then.

I mean, it's not like somebody proposes to implement NTFS inside the FAT
filesystem kernel module because distributors (or data centers) tend to
disable the NTFS module?!

How is kernel development these days constrained by what some users may
or may not put in their Kconfig?  If they want a given feature, they
must enable it.

This discussion was about why iptables UABI still matters.

And I'm trying to explain to you one of several reasons why it does.

Also, instead of saying "They decided to not use NFTABLES, oh well
that is their problem" it might be more beneficial, especially in the
long term for netfilter, to think about "why".

OK, so reading between the lines you're saying that nftables project has
failed to provide an adequate successor to iptables?
