You've pretty much described it. Setting to outputs works just as well and
requires less hardware. Also it has less of chance of screwing up if its
TRIS bit flips. Consider if you have a grounded input and it flips to a high
output because of a glitch. You now have one burned output port. However if
a disconnected output flips to an input, You'll probably be OK.

Just some thoughts.
