How do I identify and remove legacy system extensions that Catalina warned me about? I have tried the program uninstaller, but I don't think it removed everything. Does this mean software installation will convert to a sensible package management system that will record all changes to the system and be able to remove them without depending on vendors to correctly program uninstallers?

In your dreams. No, what's going to happen is that Catalina's successor will prevent those system modifications to begin with. There won't be anything to remove.
If you are motivated to remove them now though, they can be found in System Information > Extensions. It's a sortable list so start with those not obtained from Apple. Look for 64-Bit (Intel): No. Its Location is on the next line.

Most of them don't. I'd be hard pressed to come up with more than two examples that work with complete effectiveness. Ironically they're uninstallers for two of the worst pieces of junk anyone could inflict upon a Mac.

Legacy System extensions are not related to 32-bit software. Apple has said that all kernel extensions will be deprecated eventually. But certain APIs are being removed sooner rather than later. Those are the ones that are displaying these messages.
You can see the initial list here: https://developer.apple.com/support/kernel-extensions/
I don't know of any way to find extensions that use the affected KPIs. I think this is determined when the extension is loaded.

You aren't supposed to remove them. You are supposed to contact the developer and request an update.

Why not? Please be specific.

That is the idea.

*lol* it's a nice dream though. If everyone just used Debian, Debian would work for everyone....
Why are you trying to remove it. Don't you need the extension for software you're currently using?
You don't need to do anything right now. It will continue to function just fine in Catalina.
How do I remove legacy system extensions?
