I don't think anyone doubts that you have tons of experience with lots of
customers.

However, there are very important differences between anecdotes and proper
statistical studies.

There are any number of reasons for why those might differ in meaningful
ways.
There could be populations which, for whatever reason, don't overlap with
your set of clients, with different characteristics.
There could be an inherent selection bias, in how your clients choose you
or how you find your clients.
Certainly, the size of your client set, is not very likely to be anywhere
near large enough to be statistically significant, compared to the number
of domain registrants worldwide (hundreds of millions).

What folks are trying to say is, in order to build rough consensus, which
is how the IETF works, it helps to have something (anything) to support
your assertions, preferably something that can be easily confirmed
([citation needed]).

And, does the use case you are concerned with, actually need to be at the
TLD level? Would something like "internal.zz" not be just as suitable,
assuming you concur with the ".zz" usability? (Substitute arpa for zz if
you prefer.)
