Thanks, Corinna. I am in favor of option #1 and if the package gets
blessed I will be happy to maintain it.

WinFsp implements the agreed upon mapping (S-1-0-65534 <-> 65534). Cygwin
does not implement the mapping yet, which effectively means that 65534
gets mapped to -1 (Unknown+User, Unknown+Group). Here is a mini-session
with SSHFS with mapping and not mapping the local user to the remote user.

My apologies. I did not understand that you were waiting on an answer from
me.
My preference is for nodomain+nobody, primarily because the individual
components “nodomain”, “nobody” describe the lack of domain and username
when read in isolation (i.e. not in the construction nodomain+nobody). But
WinFsp does not use these names (only the SID’s/UID’s) and you, Corinna,
as the Cygwin lead are more qualified than me to choose what fits Cygwin
best.
Many thanks!
Bill
