Hi there editid0,
You may not be aware of this but there are two standards for mapping sidewalks(pavements) on osm. One uses tags on the road way and another maps them as separate ways like that ones that you deleted. The ones that were deleted were rather poorly done and and out of place so so there nothing really lost by deleting them in this case but you should add a sidewalk tag to the roads as a replacement so no detail is lost. you can read more on the wiki here:

hope this helps and feel free to ask any questions you may have,
kind regards,
kits
