Public bug reported:

As opposed to metadata or other attributes of an instance tags can be
set very early in the instance lifecycle. This will eventually lead to
issues if the boot process makes use of these tags because setting them
before boot will be a race condition. And there is a proposed spec which
intends to do exactly that, use tags in the scheduling process.

To be consistent and to avoid future racy behavior instance tags should
only be settable after a boot request after it has gone to ACTIVE
status. Passing instance tags in as part of the boot request would be
desirable behavior but requires a spec and is outside the scope of this
bug.
