And that would be perfectly acceptable in my application too, thinking
about it, though I like the idea of being able to power up the servo
drives independent of the main contactor, just so that I can delay it
until the VFD has come up.

I think that I will also look into using this as the main contactor,
as it is cheap and I can buy it on the way home:
