I like that too!  Especially if #1 can be baked into pkgsrc.

I'm more inclined to want to use #1 on the likes of a from-scratch whole
system like NetBSD, while using go-bin on something like Darwin seems
quite natural and expected -- one prime reason I use macOS in the first
place is to delegate the maintenance and building of a majority of the
software to other people.

Heh.  Building three go compilers takes less time than building almost
any other general-purpose compiler in the tree!  (or the CMake monster
alone for that matter -- I hate it most of all and will not ever use it)

In the original proposal Russ jokingly said:

    The next obvious entry in the sequence after Go 1.4 and Go 1.16 is
    Go 1.256, followed by Go 1.65536.

Even if the sequence ended up being prime numbers it wouldn't be so bad!
