What about allowing the user to specify an strategy to calculate this, even when all tiles have different scale_x values? Same applies to scale_y. And pixel height and width. Something like the '-resolution' flag in gdalbuildvrt.

What do you mean by "strategy to calculate" ? Can you make an example ?
If all tiles have the same scale a constraint would be appropriate and
expose that information in the raster_table already, no ?
