Nesting is indeed limited to one CTRL-O. Using CTRL-O while already in
Insert mode because of a CTRL-O doesn't make sense thus it's not
supported. Mainly because users would get confused because of all the
nested modes. Hitting Esc and not getting back to Normal mode already
is confusing if you didn't remember exactly what you were doing.

I suggest you assume Vim does not have bugs and make it work like that.
When you can't make it work we need to reconsider.
