We have to draw the line somewhere just like every other company with software they make. Go and ask Adobe if they could help you with Photoshop v1 and you'll get a stony silence or a suggestion to update. The number of support topics for 3.0 slowed to a crawl as everyone was moving to 3.1/3.2 as they are so much better. No more coding for MODs and they are responsive and most hosts are updating their php version so you'll find their servers won't run 3.0 anyway. As a result, we closed support for 3.0. You're perfectly entitled to keep running it yourself but we don't support it any more. It's time to move on.
To do a brand new installation now with 3.0 is bonkers.
