A \ is a shell escape. Every level of shell consumes one level of escape. For every session of a shell every example "\ " becomes " " and every example of "\\" becomes "\".
The raync command line is a mix of local shell commands + commands run via a remote shell via ssh. The simple fact is that if only \ escapes are used, the local shell will utilize those escapes and rsync will never see them. For every level of shell an escape \ does its job. If you want rsync to interpret a space char as other than whitespace then a \ is one way to do so. But one we are talking about the other side of an rsync we are talking about a local command line that consumes a \. Then we are talking about a remote command line that consumes another \. So, within the -e parameter, multiple stacked \ characters are required. Simply put, it is absolutely absurd to \ escape an rsync command line while interpreting the subshell -e parameter and the remote shell parameters the same way. At best you are insisting that ssh do something entirely nonsensical while ensuring that the first s in "ssh" is interpreted as an "s".
