[QGIS-Developer] Processing CRS Warnings useless?

[matteo]

Hi devs,

testing the new release I notice that in the Processing options there
are still the 2 options to warn the user if the CRS among layers don't
match.

Processing is correctly not warning me with 2 layers with different CRS
during a normal difference and intersection operation.

Isn't it useless to have this option with the new auto-reprojecting system?

Thanks!

Cheers

Matteo
