Some feedback on the settings

1. I do not like experimental in the name, in the description of this setting we should say it is experimental not in the name. I see we already do this for some other settings but I feel like it is wrong, because if one day we decide it is not experimental any more we have to change the setting name thus breaking behavior
2. The reason why a user shuold change this is not really explained in the description
3. Could we have "auto" as the default version so the terminal could automatically try to decide the best strategy

1. I expect the setting to go away and the only option/default being dynamic eventually.
2. Will fix
3. I don't think we need to do this given 1
