Residential protector's > 20' from service 800.100(A)(4)

[gene6]

Greetings Mike and grounding engineers and experts.
I would like to make sure I am understanding, in plain English, what the NEC is requiring for communications grounding protectors (cable / landline phone / satellite dish / wifi antenna) where the 'primary protector' or DMARC box is located more than 20 feet from the grounding grounding electrode conductor at a two family dwelling.
I am on the 2017 NEC if that matters.

800.100(A)(4) Says:

(4) Length. The primary protector bonding conductor or
grounding electrode conductor shall be as short as practicable.
In one- and two-family dwellings, the primary protector bonding
conductor or grounding electrode conductor shall be as short as
practicable, not to exceed 6.0 m (20 ft) in length.

Then it has this exception

Exception: In one- and two-family dwellings where it is not
practicable to achieve an overall maximum primary protector
bonding conductor or grounding electrode conductor length of
6.0 m (20 ft), a separate communications ground rod meeting
the minimum dimensional criteria of 800.100(B)(3)(2) shall be
driven, the primary protector shall be connected to the com-
munications ground rod in accordance with 800.100(C), and
the communications ground rod shall be connected to the power
grounding electrode system in accordance with 800.100(D).

So for example if a cable demarcation box is more than 20' from a service, to comply with the NEC;
1) A 5 foot ground rod gets installed at the cable dmarc box.
2) A #6 gets run from the GEC to the ground rod
3) A ground wire sized not smaller than #14 and not smaller than the circular mils of the sheath (telco uses #10) runs from the demarc box to the ground rod or the #6 bare.

Are there any exceptions to this? Would there be any time a cable company could legally install a coax cable drop & dmarc more than 20' from a service and not be required to do the above?
Also does a exposed hose bib more than 20' from the service GEC count, with no other GEC's visibly attached, as a compliant connection point on the ground electrode system ?
Thank you for your comments.

Correct on first paragraph

Second on exceptions,
Telecom companies are not subject to the NEC. The NEC requires an intersystem bonding point to make it easier for them to bond
On the hose bib, many years ago it would but not under current codes, as interior piping may not be metallic

Thanks Tom, I am not sure what the regulations are like out west where you are, but I did get my answer from the source, the water pipe can no longer be used and they prefer to move all the com drops close to the main GEC if possible.
In NY the regulations are kinda circular and while 90.2(B)(4) states in part
"Installations of communications equipment under the exclusive control of communications utilities located
outdoors" are exempt, long ago back in the Bell days before NYNEX those the regulate telcom explicitly pull in article 250 and 800 of the NEC in the telcom utility regulations, which also extend to what was cable television or what we now call broadband, and it has not changed. I think its because once your connecting to a building your not under 'exclusive control' anymore.
