[sdiy] Covers / shroud for unused header pins?

[Tim Parkhurst]

How about a dab of silicone (RTV)? Would cover the pins, and could be
peeled off later if the connector was needed. Or maybe just a piece of
masking tape. That would stay in place for a while (although it might dry
and fall off after a few years).
