Yes... But it's easy to configure and performs extremely well.

The VPNSM normally doesn't do GRE. (It can take over the tunnel
interface if the Sup720 can't do the tunnel in hardware, but I
don't know when that would happen).

Also, today you should use a IPSec SIP/SPA instead of the VPNSM,
which is dead in the water (SXF will be the last software to
support it, I'm told. Modular IOS doesn't and won't. SRA doesn't
and won't).
