Marvel is trying a different approach with their Echo series.

It will debut a new spotlight line, with a different approach to continuity.

Essentially, the new sub-category of Marvel is a branding for standalone fare, versus series and movies that connect to the greater Marvel Cinematic Universe.

The sub-category gets its name from an anthology comic book series first introduced by Marvel in 1971, which featured new characters that readers didn’t have to fully commit to over several issues.

The news was announced at a Friday-night screening of the first two episodes at The District at Choctaw Casinos & Resorts in Durant, Okla. as part of a larger Choctaw Day celebration.
This may be a good idea to signal that a project is accessible.

It could be argued that this is similar to Netflix's Defenders series, set in the Marvel U but separate. Although those series were interconnected, and didn't feature any actors from other Marvel projects.

There may also be identity politics pushback that Marvel's advertising that a series about a disabled indigenous woman is inessential.

I think it's healthy for the Marvel Cinematic Universe to highlight that a project is within that world, but not really part of the storyline for the big bad who is going to take multiple Avengers films to defeat.
