Yes, true and there are also several touring tires (meant for cargo bikes with ETRTO507 wheels) but all 50mm wide or more.
What is missing is 40mm wide or less high performances tires (there was a Schwalbe Kojak with decent performances when the Helix project was started in 2015, but that size was discontinued by Schwalbe), its the reason why Helix asked a small company to make a special narrow lightweight tire for Helix but, as far as I know, its only available from Helix?
Note also that most BMX tires since they are not meant to be used on open roads have a limited puncture resistance.
