Yes, but still when an average user will send any amount of bitcoin to someone, electrum by default will create two outputs, one to send the amount that you send to the other address and the other output to send the entire balance of the wallet to the change address. So this will automatically combine all of your UTXOs to the change address.
Reading this i thing that sparrow wallet have better coin control, you can avoid this easily in that wallet.
Not everyone know about coin control feature and not everyone is techy (or even willing to) to do all these complications.
They should know that, Well at least users who take care about their privacy.
