Duh; I forgot that it's 6.3.0 that's imminent, not 6.4. There isn't
any fundamental reason why it can't be done within 6.x, as it's not
externally visible.

We can't easily merge changes, but 7.x could be essentially unusable
for a long period. We may not be able to leave users with 6.3.x for
all of that time.

[I see the process as something akin to renovating a house, at the
level of stripping it down to bare brickwork: no wiring, no plumbing,
no windows. You aren't going to be able to live in it while it's in
that state.]

We don't necessarily even need a GUI. For testing, an image viewer
that automatically updates whenever map.png changes would suffice.
