Yep, and that's what I've done in my request_filter implementation:

https://review.openstack.org/#/c/545002/9/nova/scheduler/request_filter.py

Basically it allows any suffix to 'filter_tenant_id' to be processed as
a potentially-matching key.

Note that I'm hoping we can deprecate/remove the post filter and replace
it with this much more efficient version.
