Yao, Please look at draft-herbert-6man-eh-limits and RFC8883. The draft defines limits for things like maximum IPv6 header chain and maximum extension header size. The RFC defines ICMP errors that can be sent if a limit is exceeded.
These can be applied to easily discover what the maximum IPv6 header length is in a limited domain (like segment routing domain). A host would send packets with extension headers, could be probes, to a destination. If routers in the path can't handle the size of the IPv6 header they can drop the packet and send an ICMP error per RFC8883.
