Legally, by licensing their changes under "GPLv2 or later", these
people have given you permission to use it under the GPLv2 in
pdns... Not that I suggest you be impolite and don't remove their
code if they would prefer so.

This is totally understandable, but this means that once you have seen
GPLv3 and like it, you still need to get permission for GPLv3 for all
contributors... which may be harder than you think. E.g. mozilla
hasn't yet managed, after literally *years* to track everyone
down. People change emails, die, change jobs (and become astronomers
or carpenters), become Buddhist monks in Tibet, ...

Unless you collect permission from contributors to relicense their
code under later GPL version, *before* you integrate their
contribution. But then they - if they are likely minded to you - will
have the same problem with you as you have with the FSF: Wanna see the
new version first. Ugly situation, I fear.
