No worries. As long as the quality of the database is maintained.

...Or you could rectify your erroneous edits yourself.

You've mapped for the renderer which is actively discouraged. OSM is a database from which many renderings are derived. Just because certain features a hard to see in one doesn't mean they're not prominent in another.

There is no pedestrian section. Motorists can driver right upto the bollards

Anybody know if these rail tracks have be removed completely?

Hi
Already labelled

Hi
As before, these are already labelled.

Hi
Isn't Eastwood a collection of houses (which already has a label)?

Hi
Is it that shape? Aren't there more than one building?

Hi
It requires a building=* tag instead of landuse.

Hi
The restaurant already exists as a building polygon in OSM

Excellent. Could you correct it please.

Hi
There's already a John Wood House. way/89231070

Is that the block of the student accommodation?

Hi
A detailed household depot already exists. If public can't enter the bit you've just mapped would it better as a separate polygon? Is it for commercial companies?

Your addition also doubles up landuse=industrial.

*Western end

To check:
way/509695171

Doe this bridleway join into a footpath? Unusual if it does.

Actually it is for railways. They're not rendered & should be transferred to Open History Map.

If buildings are demolished they should be removed from OSM as it's not a historical map.

I'm confused now. Is or isn't the crescent oneway to vehicles?

You should have "researched" before adding features. You could of done it "sooner" but instead you went on to add further chainsets before being blocked. Your blocks are for a reason. Please try & comprehend why.

I've just added the route over Ashton Bridge. I've tweeted MetroBus to confirm that section's a guided busway: way/509467560

I took the tags from Cambridge except I've kept is a construction for now:
