I am going to assume that the part where you say "every X11 request must be a
multiple of 4 bytes" is specific to the implementation, the protocol says:
Every request consists of four bytes of a header (containing the major opcode,
the length field, and a data byte) followed by zero or more additional bytes of
data.
So every request is four bytes for header + data, if it has to be multiple of 4,
then the text in the protocol should be updated to reflect this.

https://www.x.org/releases/current/doc/xproto/x11protocol.html#request_format
already says the length of a request is defined in "units of four bytes".
