I am still only one using global swatches to ease workflow?
When changing global swatch and color value matches existing color, It shows error window that I have to close twice. And then when i got to change swatch name or try to close swatch changing window I gate same conflict message once more.
How is that reasonable?

All day long when changing global swatch definition values I have to slam my keyboard for random value, otherwise there will be conflict and often I have to start all over again.

Egor:
"So I'd like to have this as a sticky checkmark that
A) will remember if a user wants auto-naming
B) will auto-name a a swatch when ticked
Or maybe a separate 'Auto-name' button and a separate checkmark better."

Similar checkmark as Layer menu has for "Paste remember layers" would be nice.

Example of optimum Illustrator workflow with global swatches.
Button smashing to get unique name fast, when opening global swatch first time.

If folder name already exist in windows it put (2) in the end. It was invented at least 30 years ago. You can do it too.

I need ability to turn off auto renaming swatches permanently.
Changing swatch color definition or just previewing the swatch color change prompts an error about there being such name in use already. That often means even if I change the swatch name to something unique (smushing my hand on keyboard) it does not change the color value, and I have to start all over again. It hinder global swatch workflow tremendously.

That is clear now, I see. True, that is the issue I met myself. Sometimes different swatches indeed have the same color values, but should have different names.

And also sometimes you want Ai to automate the name instead, form a random gibberish you or another artwork had — but there is no way to force the auto-naming!

So I'd like to have this as a sticky checkmark that
A) will remember if a user wants auto-naming
B) will auto-name a a swatch when ticked
Or maybe a separate 'Auto-name' button and a separate checkmark better.

How do you like it?

Does no one use global swatches? It is awful that I have to hit random keys to get unique swatch name, before I start changing its color. Otherwise if it matches some other swatch automatic naming then there is conflict and all edits are lost and I have to start all over again.

Egor, don't make copy of same swatch.
Lets say you have two different global swatches that have names from their values. When you change one swatch values same as other then you get instant conflict.

I don't get it. AI adds a number to a name if you try to create a swatch with same colors.
So you get 'C=0 M=50 Y=0 K=0 1'. If you try to delete ' 1' and save it will still be added to avoid matching.
So when does the message you talk about come up?
