Correct me if im wrong, but yes certain tools are required (now). But after v30 and with data in the op_return you won't need "certain tools" at all. It will be right there in your face.

No.
Even with OP_RETURN, the data is still just hex unless you intentionally decode and render it. Bitcoin Core doesn’t suddenly start “displaying content in your face” just because the limit was raised.
You still need tools (or scripts) to parse and interpret the data - just like you always have. The node doesn’t care what the data is. It just sees bytes.
Raising the limit doesn’t change how nodes behave. It simply allows for more bytes in a null data output. The default policy is still conservative, and content isn’t displayed unless you go looking for it.
