Following redirects is insecure for sites that let users configure redirects.

Every time you trade away security like this, you make it more likely
that host-meta will be unusable for secure metadata.  If host-meta is
unsuitable for secure metadata, folks that require security will just
work around host-meta by creating a "secure-meta."  I can't tell you
which of the security compromises will cause this to happen.  Security
is often a "death of a thousand paper cuts" that eventually add up to
you being owned.
