See, your confusion lies in believing that load data comes from major manufacturers. It doesn't any more. They provide only a couple of loads, and generally not at full pressure. They know everyone who takes reloading seriously just uses Quick Load, so why bother? The few manufacturers that do provide comprehensive data mostly just use Quick Load too - the entire Berger manual is just Quick Load results.
Technology has moved on, and left you (and the .30-06) behind.
Most load data DOES come from manufacturers because most ammo shot is factory loads. Non-handloaders far outnumber handloaders. For them the load data is limited to external ballistics, but that is OK because the loads are pressure tested by the manufacturers and pretty much all the shooters are interested in is the external ballistics and bullet construction.
For the handloaders, once again most data comes from the manufacturers as relatively few use QuickLoad.
The set of shooters that use QuickLoad is a tiny percent of all shooters and a small minority of handloaders.

No, I'm not a Ruger bigot - just an unabashed fan of their revolvers, M77's and #1's.
