Sorry, but I do not think this is a much better option.
The section quoted in the article is in New Mexico proposed by the New Mexico Touring Society.
(BTW, I had read and posted earlier in that article)
Other than the dogleg up to Santa Fe, it does little to alter the service road/interstate issue.
Here is a rough descriptionn from their website:
Proposed Route Segments (Described from West to East)
Segment 1: Arizona border to Gallup (including Gallup). The route follows NM 118. 22 miles.

Section 1 - Fine if you like service roads - original sections of Route 66.
Section 2 - NM 602 has fairly heavy traffic (4000+), hills, rideable rumble strip shoulders, NM 53 nice.
Section 3 - More service roads and some I-40 riding.
Section 4 - Yikes!?! Interstate and urban streets. Then Old 66 up Tijeras Canyon as service road.
Section 5 - NM 14/Turquoise Trail is lovely, but busy. (5000+) No shoulder mid section.
Section 6 - Santa Fe tricky to negotiate and expensive. Old Las Vegas Hwy very busy. Pecos nice.
Section 7 - US 84 - good road, low traffic, shoulders. Nice bluffs northern end.
Section 8 - Back to interstate and service road riding.
Without doing a mile-by-mile, I'd say more than half of the route is
Interstate riding, service roads, high traffic, or congested.
Since Bike Route 66 is more than just a historical fantasy, but also a major southwestern connector -
It seems that a route which offers great roads, scenery, and the "feel" of a tour in 1950 would be preferable.
For example, NM 104 between Tucumcari and Las Vegas is stunningly empty -
Great mesas, state park, services on both endpoints.
Taos is very bike friendly, historic, and fairly easy to bike into and out of.
Coyote to Cuba is lovely, quiet riding in high pine country.
Riding via Cuba and Crownpoint allows one the option to off road to visit the Chaco ruins.
And you can soak up the Route 66 kitsch in Gallup.
Hey, I like the Route 66 diner in Albuquerque, too.
But why ride with the roar of the interstate and fight city traffic - -
When you can have dinner on the Taos Plaza?
