Hello.
When mapping straight sidewalks there's no need to add intermedia nodes along the way. Ultimately it should be a straight way from curb to curb with only nodes present are intersecting with any other ways.
Also please remember to tag curbs. If you can not tell what kind of curb it is from satellite imagery, you can just tag it as a generic curb, and that will be prompt apps like StreetComplete to fill in the missing details for people who are on the ground and can survey it.
