What's the level f support of PF wrt IPv6 Extension Headers?

pf.conf(5) talks about an implicit block rule for packets employing the
routing header, but I've not been able to find anything about e.g.,

* Filtering packets on a per-EH-type-occurrence (e.g. "block packets
that contain a Destination Options Header")

* Filtering packets base on the EH size

* Filtering packets based on the number of EHs they contain (e.g., drop
the packet if it employs more than 5 EHs)
