Yes, correct
It would only take 1 user to do this
and bring unwanted attention
would simply not be worth the risk TBH
there is little benefit to its use
just mixing coins between own accounts
you could even lose privacy
as all accounts then get linked
Splitting coins to new fresh addresses provides better privacy
The potential downside, far outweigh the upside
Users have to be smart about UTXO management, and this is where the freeze coin feature comes in handy. If you don't want to merge outputs, then freeze those coins, or send to a new wallet account. Electrum wallets can have multiple separate accounts.

where as mixing between own addresses is not IMHO
