So a PR could be fairly straightforward to just add a new entry to the enum with the appropriate settings. Changing the switch to an exhausive pattern matching would also help catch any net-new issues.

Do you mean a default case could catch both Stroustrup and this new proposed style OTPS as have the same values?
