Would I use this if I host my own postgres and want to use replication for „real time backups“ into a hot standby?

Not OP - but definitely no. In such a case use just physical or - if you have special use case - logical replication that’s built in.

		I agree. pgwire-replication is useful when you need to build a customized and closely controlled pipeline. In fact, it will give you the first part of handling the data (reading from the source), you still need to implement the rest yourself.
