While you tell the kernel to lie about the "features" we support, the only place this is used in FreeBSD is in the kernel (there's only a difference if you set it to 2.4.x), and the current value is strictly speaking a lie too when seen from a linux-program (not all features of the currently emulated version are really available). The only port which comes to my mind (which doesn't mean there's not another port which does something like this) which changes the running config of a system is postfix (mailer.conf). Before it does this, it asks the users if he is OK that the config is changed, it's not doing it silently (by default). Most of the ports do not automate something like this. Personally I would not automate it. If you automate it I suggest you ask the user if it is OK and don't assume it is OK by default. Info: in the past we didn't do this, first we change the value in the kernel and then we switched the default on supported FreeBSD versions. If you want to say that we could see this case differently as in the past we had to add some kernel code to run a more recent linux userland, I would not disagree (read: ivory tower perspective = I think we should change the kernel first; pragmatic point of view = I don't object changing the default)...
