Open via in pad is not reliable for many issues, including z-axis stress
introduced the lead attach during operating temperture exursions.

The design should be reviewed first to look into moving the via which is
generally a good option.  A conductive via fill can also be used to produce
a flat landing site for soldering.  The cost for conditive via fill often
time outweights the cost to re-layout the package.
