Yeah, well, what do you expect?   NetBSD is, by definition, the best
host platform for its own development since it is a proper self-hosting
system.

Now that NetBSD (almost) supports full cross-builds, you're almost
certainly wrong on that point, and more importantly you're definitely
wrong if the alternate platform is running on hardware that would itself
support native NetBSD.

Indeed soon any existing natively supported platform will suffice for
hosting NetBSD porting to some other platform.

The assumption should be that the filesystems on which the source files
will be stored are similar enough to the native host environment that no
changes be required in the source tree hierarchy and naming.  It would
seem that necessarily rules out use of antiquated systems, even when
they've been coerced too look somewhat unix-like, such as Cygwin, U/Win,
etc.
