How come we cannot lock txt msgs from being auto-deleted?

How come they no longer allow people to lock txt msgs from being auto-deleted in Android 4?

My old Continuum with Android 2.2 allowed me to lock text messages.
This seems to be a downgrade rather than an upgrade.

What auto-deletes text messages? Do you have to turn on auto-delete cause I've never had one get deleted that I didn't actively delete.

The phone auto-deletes them when new txt's come in. Auto-delete is enabled by default, without it then I bet this stupid phone would crash with 1,000 txts in it.

My old Continuum with Android 2, if there was 200 txts in it then it would not receive any new msgs. And auto-delete would not always work, but at least when it did then it would not delete the locked msgs.
