So far, looks good, so I'm hopeful :)

Bit more than that. Well, what's been asked for is the kitchen sink.
Apparently the PCI auditor said: «all private keys must be stored
outside the server».
Our main use for keys is straight GPG, for decrypting files, both
manually and automatically, but there are others involved, like LUKS,
S/MIME (also for files), Apache, ssh...
LUKS I've now done, using the GPG key in the Nitrokey and an agent
service to decrypt its passphrase non-interactively.
My next worry is checking what I can do if we need several private GPG
keys. Eg, have a bunch of NitroKeys?

Yes, it's definitely where I'm going tor the for the other non-GPG kinds
when I get to them. In all likeliness, once I'm fully satisfied the
hardware is up to the task, Nitrokey will be hired for some expertise in
ironing the details. At least I'm going to push for that.

Technically, not difficult, but anything needing compilation is a huge
amount of maintenance and red tape overhead.

Yes, quite. I'll continue pushing for that elusive middle ground :)
