Ext_rom unlocker? This is going to sound silly.

I realize this might be a strange question, but can someone tell me why we need the extended_rom unlocker? I have an orange switzerland branded spv m5000, and I hard reset it today. After it came back up, I installed GSfinder as an alternative file browser, and entered \extended_rom in the adress bar.
Without any trouble, I was browsing the content of the extended rom. Does this mean that the ext_rom is unlocked by default on my device? Or does the effect of the unlock tool survive a hard reset?

Can you write into the Ext Rom?

Yup, no problems. I just copied my cooked ext_rom in there, and hard reset again. Works perfectly.

Maybe this detail is important: The first hard reset was necessary because I flashed the new orange switzerland updated rom two days ago. I let it run completely through the default installations, to see what was new, then hard reset /soft reset it to avoid it installing the orange stuff. Then I wanted to run the ext_rom unlocker to change to my cooked version, and noticed that the ext_rom was already accesible.
