Well, why *not* ground it ? :-)

It's no major job and as you say, most recomend
that you do so.

If I'm not wrong, "LVP-on" is the default status on
a newly-erased part. So if the LVP pin is floating
some funny things could happen, even if I think
that "fry" isn't one of these... :-)

Some programmers (like Wisp628) has a connection for LVP
(even if it does not support LVP as a programming method)
just to keep sure that it's kept low during HVP programming.
The Wisp628 set it's line into high-Z after programming so
it doesn't interfere in the applications use of the LVP pin.
