This is probably heavily dependent on the requirements you have on
that server:

- If you absolutely depend on data integrity, it's better to not boot
  it and drop you into a rescue shell.

- If you absolutely depend on uptime and remote accessibility,
  bringing up a degraded RAID is the way to go.

Not having physical access to my server myself, I much prefer the
second one, but I do appreciate that it defaulting to the first
alternative is a safer default.

I would welcome if this was configurable, though.
