* RFC 2578 (STD 58) says this about OBJECT IDENTIFIERs:
*
* > 3.5. OBJECT IDENTIFIER values
* >
* > An OBJECT IDENTIFIER value is an ordered list of non-negative
* > numbers. For the SMIv2, each number in the list is referred to as a
* > sub-identifier, there are at most 128 sub-identifiers in a value,
* > and each sub-identifier has a maximum value of 2^32-1 (4294967295
* > decimal).
*
* So a legitimate OID according to this RFC is at most (32 * 128 / 7),
* i.e. 586 bytes long.
*
* Ref: https://datatracker.ietf.org/doc/html/rfc2578#section-3.5
