Hi Hajo
I see your point but but I see it totally differently. The board
layout and silk screen is not WRONG and does not need alteration
which would cause confusion. Everything is correct for the 2N7000,
the BS170 can be supplied as an alternative and adequate information
is provided for the correct orientation of this substitute.
We can only get irritated with the manufacturers of the devices if
we wish lazy people to be able to mindlessly thrust devices in any
way round.
Heat sinking as you say is not essential and dissipation can be
dealt with by extra devices inserted in the positions provided.

The 2N7000 and BS170 are ,
used for low-power switching applications. The two are nearly
identical except that the leads are arranged differently and the
current ratings are somewhat different
