No, the problem exists also if you only load the german patterns.

Well, as you mention "base mode": This reminded me that I had to
force base mode to get my reencoding to work in latex. So I tried in
context + latex/luaotfload (with german hyphenation patterns):
\font\test="name:TeX Gyre
Bonum:mode=base:featurefile=bonum.fea;+kern"
and
\font\test="name:TeX Gyre
Bonum:mode=node:featurefile=bonum.fea;+kern"
And bingo: with mode=base it works in both formats, with mode=node
the kern disappears. Without mode declaration the kern disappears in
latex.
So I think it isn't true that the manual of luaotfload claims "By
default mode=base is used".
