since commit 8e1fb37 (v1.8.0) there is check enum binary backward compatibility so we are relaxing this check below, versions do not have to be equal but both need to be at least 2ebde24 (v1.9.0), this will make sure that enums are always ok, but since that commit some data structures changed and are not binary backwad compatible like next hop group api, acl_capability, structs are backward binary compatible from commit aed34c8, which closest tag version for it is commit 3ff228a (v1.12.0), so min version check should be set to (v1.12.0), but some production branches do not use that high SAI version yet, some use even version v1.7.0 which then it is impossible to provide even enum backward compatibility, check those links: opencomputeproject/SAI#1297 (enums) opencomputeproject/SAI#1795 (structs)
