I've done a revert of these changes in one go to make it easier, I'd recommend reading some of the pages about highway classifications and surface tagging on the OSM Wiki, and there's plenty of places to discuss with the community if you're not sure about things.

I've reverted these en-masse back to how they were before.

RideWithGPS may only update very so often.
I also wouldn't change roads like this one to secondary, it's not a major road of any kind, it's a shortcut as most from what can be seen. I think this and the other highway class changes should be reverted, unless there's reasons for any specific one to be higher than unclassified/residential.

Hi, why have you changed this small section to secondary?

Hi, what's your justifications for changing these sections from unclassified up to secondary, a significant jump?

Hi, what's the justification for changing this quiet road from unclassified all the way up to secondary?

Hi, paved is a generic catch-all option for roads that have been properly surfaced, these roads do look like they are asphalt and should be tagged as they were before.

It does seem preferred so you can still specify what type of rail it is.

Would it be better to tag this as railway:preserved=yes? Seems to be more popular and there's been pushes to depreciate railway=preserved in the past.

Hi, is this part of a chain of computer repair places? If not, the brand tag is wrong and shouldn’t be set. You also need to format the number correctly, it should be +61 494 068 255.

My head's probably a bit stuck in some related but not as similar issue outside of OSM, thanks for confirming!

Hi, my only concern then, that website is under copyright, I'm not sure if that would be an acceptable source for edits.

Hi, this change covers a good portion of the world and involves changes to roads in Australia, what's your source for the etymology of way/36871107 and way/76808134?

Not a problem.

I'd still recommend engaging with the community just as much for a global change as you would for a more local one, you'd just obviously be able to focus on local communities instead of the global OSM community for feedback.
