I don't see any need to change what you are doing. I don't see any point making entering data more difficult for yourself.
Some don't enter detailed data and don't see the need.
Simplifying tools will *always* lose information.
Openstreetmap has a large database all your edits in this set only contributed 0.000005% of the total and about 0.005% of new nodes added daily. It is not going to effect OSM at all in any negative way adding detailed info.

The node issues and dups I have fixed already. A simple fix when you know how.

There are not too many nodes - this is great. Don't listen to the haters,
Please leave as it is.
Don't use Simplify ways in Josm. Simplify way is simply useless. It will reduce all your work and ways to a complete mess.

Well clearly the heart was in the right place on this edit. Established
One mans obvious guideline changes is anothers sweeping
I must say I have edited plenty in London and never noticed/registered it before. If I had I would likely have done the same thing.
One of the problems in large cities (maybe more so with active communities) is some things get overlooked/not acted upon as they things someone else (not you SomeoneElse) will do or has done it how we want. That and very few people have the detailed local knowledge of *all* the areas, like suburbs in London/Birmingham, etc
